I kinda like Alvaro's suggestion of an --ignore-bison-version option
to configure to suppress checking the version, but otherwise error out
if we think bison is too old.

The advantage to that is that you could manually override the automatic
check if you had reason to know it was wrong (eg, you could see it'd
misparsed the bison version string, or something).  Also, it'd make
sense to include that option by default in RPM builds, where you'd know
you had up-to-date bison output files already included in the SRPM.
