tests: drop useless requirements of gcc (plus testsuite tweakings)

* tests/libobj14.test ($required): Remove 'gcc', as we never run
the C compiler.
* tests/targetclash.test: Likewise.
* tests/ansi6.test ($required): Remove 'gcc', as any working
C compiler should be enough.
* tests/ansi7.test: Likewise.
* tests/ansi9.test: Likewise.
* tests/ansi10.test: Likewise.
* tests/lex5.test: Likewise.
* tests/lexvpath.test: Likewise.

* tests/subst3.test: Likewise.
* tests/substre2.test: Likewise.
* tests/yacc6.test: Likewise.
* tests/yacc8.test: Likewise.
* tests/depcomp2.test: Likewise.  Also, avoid clobbering user-set
CFLAGS.
* tests/lex3.test: Likewise.
* tests/ansi3.test: Likewise.  Also, avoid 'CC=gcc' in configure.
* tests/ansi3b.test: Likewise.
* tests/ansi5.test: Likewise.
* tests/autohdr4.test ($required): Remove 'gcc', as any working
C compiler should be enough.
Also, do not reject slow dependency extractors (which we might
be forced to use now that $CC is not necessarily gcc anymore).
* tests/cond16.test ($required): Remove 'gcc', as any working
C compiler should be enough.
Since we are at it, throw in few minor tweakings (mostly cosmetic,
stylistic, or consistency-related).
