testsuite: require C compiler explicitly in tests needing it

The list of the test scripts which needed a C compiler but
failed to require it explicitly has been found by running:
  $ am_explicit_skips=yes CC=false make check
and looking for tests that reported FAIL instead of SKIP.
After the present change, all those previously failing tests
either pass or get correctly skipped.

messages.
* tests/subobj5.test ($required): Add `cc'.
(Makefile.am): Set `AUTOMAKE_OPTIONS' to `subdir-objects', and
add new checking rules `test-build' and `test-distdir'.
Extend the test by building and examining the distdir, the
program, and the object files.
* tests/postproc.test ($required): Add `cc'.
Avoid the explicit `|| Exit $?' after call to configure, which
is now either redundant (e.g., when `am_explicit_skips' is
unset), or counter-productive (e.g., when `am_explicit_skips'
is set to "yes").

* tests/nostdinc.test: Likewise.  Also, make grepping checks
on `Makefile.in'.  Update heading comments.
* tests/compile5.test: When we must skip, skip explicitly,
and with a meaningful message.
* tests/instspc-tests.sh: When running in "test-build" or
"test-install" mode (as determined by the value of variable
`$instspc_action'), require `cc'.  Adjust comments.
* tests/depmod-tests.sh: Likewise.
