  tests: can fake a compiler not grasping "-c -o" -- globally in all tests
  
  The ability to easily do so will be quite important in upcoming changes
  about C compilation handling and semantics of the 'subdir-objects'
  option.  Refer to the extensive discussion about automake bug#13378 for
  more details: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378>.
  
  See also commit 'v1.13.1-34-g744cd57' of 2013-01-08, "coverage: compile
  rules used "-c -o" also with losing compilers".
  
  * t/ax/cc-no-c-o.in: New, a "C compiler" that chokes when the '-c' and
  '-o' options are passed together to it on the command line.
  * Makefile.am (t/ax/cc-no-c-o): Generate this script from it.
  (noinst_SCRIPTS, CLEANFILES): Add it.
  (EXTRA_DIST): Add 't/ax/cc-no-c-o.in'.
  (check-cc-no-c-o): New target, runs the whole testsuite with 'cc-no-c-o'
  as the C compiler (bot GNU and non-GNU).
  * .gitignore: Update.
  * t/ccnoco.sh: Use the new script instead of duplicating it.
  * t/ccnoco3.sh: Likewise.
  * t/ccnoco4.sh: Likewise.
  * t/self-check-cc-no-c-o.sh: New testsuite self-check.
  * t/list-of-tests.mk: Adjust.
