tests: expose automake bug#14560

Automake needlessly generates definition of make variables related
to C compilation when two or more user-defined suffix rules are
present in a single Makefile.am.

* t/suffix-extra-c-stuff-pr14560.sh: New test, exposing the bug.
This test is still xfailing.
* t/no-extra-c-stuff.sh: New test, check for a potential related
regression.  This regression is not actually present here (so this
test passes), but it still took place in our first attempt at
fixing bug#14560 -- so this test has proven to be actually useful.
* t/no-extra-makefile-code.sh: Improve comments, and tighten the
grepping checks a little.
* t/list-of-tests.mk (handwritten_TESTS): Add the new tests.
(XFAIL_TESTS): Add the new xfailing test.

lang, suffix rules: don't require C stuff needlessly

This change fixes automake bug#14560: when two or more user-defined suffix
rules were present in a single Makefile.am, automake would needlessly
include definition of some make variables related to C compilation in the
generated Makefile.in.

* automake.in (handle_languages): Fix logic to decide whether or not to
include definitions of C compilation related variables in the generated
Makefile.in: instead of doing so when two or more user-defined suffix
rules are seen (which is a completely bogus criterion), do so when two
or more compiled languages are used.
* lib/Automake/Rule.pm (suffix_rules_count): Remove as no longer used.
(@EXPORT): Adjust.
* t/list-of-tests.mk (XFAIL_TESTS): No longer list the test script
'suffix-extra-c-stuff-pr14560.sh', which now passes.
* NEWS: Update.
