tests: tweak and improve tests on Automake conditionals

The "avoid the requirement of a working compiler" we refer about
below is obtained by disabling automatic dependency tracking and
defining `CC' (and `EXEEXT', `OBJEXT', `CXX', etc., if needed) to
dummy values, either directly in the `Makefile.am', or by AC_SUBST
in `configure.in'.

The "cosmetic changes" we refer about below consists in, e.g.,
adding a trailing `:' command to a script, using proper m4 quoting
in `configure.in' files, adding commands that offer more debugging
output, explicitly declaring phony targets as such in Makefiles,
making use of idioms more consistent with those employed in other
tests, following the GNU formatting standards more closely, etc.

* tests/cond.test: Cosmetic changes.
* tests/cond3.test: Likewise.
* tests/cond10.test: Likewise.
* tests/cond14.test: Likewise.
* tests/cond15.test: Likewise.
* tests/cond17.test: Likewise.
* tests/cond40.test: Likewise.
* tests/cond13.test: Likewise, and make grepping of the generated
`Makefile.in' slightly stricter.
* tests/cond6.test: Extend by also running ./configure, make and
"make install".  Few cosmetic changes.
* tests/cond8.test: Likewise.
* tests/cond2.test: Do few cosmetic changes.  Make grepping of
automake stderr stricter.
* tests/cond20.test: Likewise.
* tests/cond23.test: Likewise.
* tests/cond24.test: Likewise.
* tests/cond42.test: Likewise.
* tests/cond46.test: Likewise.
* tests/cond9.test: Move more checks in the `Makefile.am' instead
of grepping make's output.
* tests/cond38.test: Likewise.
* tests/cond11.test: Likewise.  Avoid the requirement of a working
C compiler.
* tests/cond16.test: Likewise.
* tests/cond22.test: Likewise.
* tests/cond30.test: Likewise.
* tests/cond31.test: Likewise.
* tests/cond4.test: Likewise, and drop the now-useless GNU make
requirement as well.
* tests/cond18.test: Likewise.
* tests/cond19.test: Likewise.
* tests/cond22.test: Likewise.
* tests/cond25.test: Add trailing `:' command.
* tests/cond26.test: Likewise.
* tests/cond27.test: Likewise.
* tests/cond28.test: Likewise.
* tests/cond29.test: Use `unindent' function for better formatting.
Other minor cosmetic changes.  Use a `timeout' program (if it's
available) to determine whether the script takes too long, instead
of just hoping that the user will notice an abnormally long test
execution time.
* tests/cond33.test: Extend a bit.  Fix heading comments.  Few more
cosmetic changes.
* tests/cond37.test: Ensure verbose printing of captured make
output.  Minor cosmetic changes.
* tests/cond34.test: Likewise.  Avoid the requirement of a working
C compiler.  Make grepping of make output slightly stricter.
* tests/cond35.test: Quote literal dots in grep regexp.  Add extra
debugging output.  Minor cosmetic changes.
* tests/cond36.test: Likewise.
* tests/cond41.test: Do not simply check that aclocal fails, but
also grep its stderr for the expected error message.
* tests/cond43.test: Likewise (but the program being automake).
Few cosmetic changes.
* tests/condd.test: Avoid the requirement of a working C compiler.
* tests/condman3.test: Extend by using more man pages and more
manpage sections.
* tests/condman.test: Removed, it's completely superseded by
`condman3.test'.
* tests/Makefile.am (TESTS): Update.
