  yacc: warn about conditional content in *YFLAGS variables
  
  This commit fixes automake bug#7804.
  
  * automake.in (lang_yacc_target_hook): Warn if any of the relevant
  *YFLAGS variables has conditional contents (not only a conditional
  definition).  Related refactoring.
  * NEWS: Updated.
  * tests/yflags-conditional.test: Updated and extended.
  * tests/yflags-conditional-force.test: New test.
  * tests/Makefile.am (TESTS): Updated.
