>Description:
Bison is needed to compile gcc.
For example, within the target [all-gcc][c-parse.c].
However, if bison is not found during the configuration, the configure script does not complain.
   checking for bison... no
Yacc or Byacc are not installed either.
>How-To-Repeat:
Uninstall bison and remove config.cache, then rerun configure.
>Fix:
Bail out if no bison is found.
