  warnings: more precise category and message for one warning
  
  If automake detected an usage like "AC_CONFIG_FILES([./Makefile])"
  in configure.ac, it warned that such an usage was unportable to
  non-GNU make implementations.  But the truth is actually worse:
  that is actually *unportable to GNU make* itself, since it breaks
  the automatic remake rules in subtle ways.
  
  So we now reveal this breakage in a new test case, and enhance
  the warning by giving it a more precise and correct wording, and
  by moving it from the category 'portability' to the category
  'unsupported'.
  
  * automake.in (scan_autoconf_config_files): Improve the warning.
  * tests/conffile-leading-dot.test: New test.
  * tests/list-of-tests.mk: Add it.
