Instead, properly use the -E, -O, or -M options of run_make.
The occurrences of the 'run_make' invocations using output
redirection has been found by the recently-introduced maintainer
check 'sc_tests_no_run_make_redirect'.
* t/ax/tap-summary-aux.sh: Adjust.
* t/ax/testsuite-summary-checks.sh: Likewise.
* Several other tests: Likewise.

We now do so with a new wrapper shell function 'run_make()', which
relies on the use of AM_MAKEFLAGS, avoiding the use of the '-e' make
option. The use of that option (that causes the environment variables
to take precedence over the macro definitions in the Makefile) has
proved to be quite brittle in the past, causing annoying and sometimes
problematic spurious failures. This has worsened in some still
unpublished work going on in development branches. It's time to solve
the issue once and for all.
Note that we do not convert all uses of $MAKE in the testsuite right
away; we might do so in follow-up changes, with leisure, to avoid a
"patch bomb" effect (this commit is already too much of a bomb itself).
What we do in this commit is to get rid of all "$MAKE -e" invocations.
We admit that the implementation and feature-set of 'run_make()' are
far from perfect, but good enough for our current purposes. We'll
improve 'run_make()' if and when the need arises.
* syntax-checks.mk (sc_tests_no_make_e): New syntax check, guard against
the use of "$MAKE -e".
(syntax_check_rules): Add it.
(sc_tests_overriding_macros_on_cmdline): Adjust.
(lint): New, alias for 'maintainer-check', for lazy typists. Idea
backported from the 'maint' branch (Automake 1.13a).
* t/ax/am-test-lib.sh (run_make): New function. Run $MAKE with the
given command-line arguments, handling command-line override of variable
definitions in a smart way (using AM_MAKEFLAGS if a non-GNU make
implementation is detected to be in use).
(useless_vpath_rebuild): Adjust to use 'run_make', to avoid a spurious
maintainer check failure.
(yl_distcheck): Use 'run_make' rather than bare '$MAKE'.
(single_quote, append_single_quoted, is_valid_varname): New auxiliary
function, used, directly or indirectly, by it.
* Many tests: Adjust to avoid the use of "$MAKE -e", and prefer the
use of 'run_make' in few other contexts as well, where it makes sense.
Other minor fixlets while at it.

It gives the impression that they are directly runnable, as with
"./t/foo.sh", but it has been a while since that was the case. Today,
tests are runnable only through "make check" or "./runtest".
This change is for the 'micro' branch (automake 1.13.2a). It will
soon be followed by similar patches for the 'maint' branch (automake
1.13a) and the 'master' branch (automake 1.99a).
* t/*.sh, t/*.tap: Remove executable bit.
* maint.mk (sc_tests_executable): Remove.
(syntax_check_rules): Adjust.
* gen-testsuite-part: Set permissions of generated tests to
'444' (-r--r--r--), rather than 555 (-r-xr-xr-x).

This is a follow-up to today's commit v1.12.4-22-g0610fc8,
"tests: prepare to move ./defs to t/ax/test-init.sh"
* All tests: To run the common setup, use the command:
. test-init.sh
instead of the older, "historical" one:
. ./defs || exit 1
Note that the "|| exit 1" wasn't really useful, since the 'errexit'
shell flag is in effect in both './defs' and 'test-init.sh', and all
the known shells that are good enough to run the automake testsuite
do automatically exit with error when a sourced file cannot be found
(at least, they do so in non-interactive mode, which is the only
mode that concerns us in the testsuite).
* t/ax/tap-summary-aux.sh, t/ax/testsuite-summary-checks.sh: Likewise.
* gen-testsuite-part: Do the same in the generated tests.

Once, for the sake of (at least) Solaris 10 /bin/sh, we had to use
"test ! -f FILE" or "test ! -r FILE" or "test ! -d FILE" instead,
because the that shell's 'test' built-in didn't grok the '-e' option.
Note however that we still can't use "test ! -e" in the Makefile recipes
used in the test cases; that is because those recipes are run with the
shell detected by 'configure', and Autoconf-generated configure scripts
do no guarantee to find or provide a POSIX-compatible shell.
* Several tests: Adjust.
* t/yacc-clean-cxx: Adjust, and remove a couple of useless commands.
* t/parallel-tests-dry-run-2.sh: Adjust, and add invocation to
"make -n" forgotten in previous versions of the test.
* t/txinfo26.sh: Adjust, and don't bother to skip the test when it's
run in a directory whose absolute path contain whitespace: that setup
is not supported anyway.
* t/maken3.sh: Adjust, and fix a typo that could cause a minor false
negative.
* t/test-trs-recover2.sh: Prefer using 'skip_' with a suitable error
message over a bare 'exit 77'.

Now that we can assume our tests are run by a decent POSIX shell, we
can simplify our workaround aimed at having the exit status propagated
correctly to the code in the exit trap. Unfortunately, we cannot
dispense with such a workaround altogether, because it's still required
by some shells we need to support (at least Solaris 10 /bin/ksh and
/usr/xpg4/bin/sh).
For more information about the need of that workaround, see the entry
about 'trap' in the section "Limitations of Shell Builtins" in the
Autoconf manual:
<http://www.gnu.org/software/autoconf/manual/autoconf.html#trap>
The new workaround has been tested successfully with the following
shells:
- Bash 4.1
- Bash 3.2
- Bash 3.0
- Bash 2.05b
- dash 0.5.5.1
- dash 0.5.2
- AT&T Ksh 93u (from official Debian package)
- MirBSD Korn Shell 40.2 (from official Debian package)
- Solaris 9, 10 and 11 /bin/ksh
- Solaris 9, 10 and 11 /usr/xpg4/bin/sh
- NetBSD 5.1 /bin/sh
- NetBSD 5.1 /bin/ksh
* t/ax/test-init.sh (Exit): Rename ...
(_am_exit): ... like this.
(exit): New alias for '_am_exit'. We cannot simply redefine 'exit'
as a shell function, because some shells (dash 0.5.5.1, Solaris 10
/bin/ksh and /usr/xpg4/bin/sh) do not allow it.
(_am_exit, trap): Add extra escaping for 'exit' calls, to ensure we
really invoke the 'exit' builtin and not our alias with the same
name.
* configure.ac: Check that the shell selected to run our testsuite
supports aliases named like shell builtins.
* t/REAMDE: Adjust.
* All tests: Adjust, by simply using 'exit' instead of 'Exit'.
* t/self-check-explicit-skips.sh: Adjust: the first usage of 'exit'
after it has been redefined as an alias must be on a new line w.r.t.
that where the alias is defined, in order for the redefinition to be
honored.
* syntax-checks.mk (sc_tests_Exit_not_exit): Delete.
(sc_tests_exit_not_Exit): New.
(syntax_check_rules): Adjust.
(sc_tests_automake_fails): Simplify the recipe a little.
* Several tests: Remove now useless spurious quoting once required
to placate the 'sc_tests_Exit_not_exit' maintainer check.
* gen-testsuite-part: Likewise. Also, avoid uses of 'Exit' in the
generated scripts.

This will help our transition from 'serial-tests' to 'parallel-tests'
as the default test suite driver enabled by a TESTS assignment in the
input Makefile.am. Note that that change of default will only take
place in master, though.
* defs: Pass the 'parallel-tests' option to the AM_INIT_AUTOMAKE
invocation in the created 'configure.ac' stub, unless the variable
'am_serial_tests' is set to "yes". Don't pay attention anymore to
the 'am_parallel_tests' variable, that's obsolete now.
* defs-static.in: Warn if the 'am_serial_tests' variable is set in the
environment; conversely, don't warn anymore about 'am_parallel_tests'
being set in the environment.
* Makefile.am (AM_TESTS_ENVIRONMENT): Nullify the 'am_serial_tests'
variable instead of the now-obsolete 'am_parallel_tests' one.
* syntax-checks.mk (sc_tests_obsolete_variables): Also warn against
uses of 'am_parallel_tests', which is now deprecated in favor of
'am_serial_tests'. Similarly, if a use of 'parallel_tests' is seen,
suggest using 'am_serial_tests' instead, not 'am_parallel_tests'.
* gen-testsuite-part: Now that we use the 'parallel-tests' by default
in our tests, we need to completely change the logic and semantics of
generation of sibling tests for those tests that check the Automake
generated testsuite harness itself. Do that, and give a complete
explanation of the new logic and semantics in the relevant comments.
* t/README: Update.
* Lots of test cases: Adjust.

When we (soon) convert the Automake testsuite to a non-recursive
make setup, we'll have to fix the entries of $(TESTS) to be
prepended with the subdirectory they are in; this will increase
the length of $(TESTS), and thus increase the possibility of
exceeding the command-line length limits on some systems (most
notably, MinGW/MSYS). See automake bug#7868 for more information.
Thus we rename the 'tests/' subdirectory to 't/', and each 'x.test'
script in there to 'x.sh'; this way, the $(TESTS) entry 'foo.test'
will become 't/foo.sh', which have the same number of characters.
