or rather in the latest version of common/m4/gst-parser.m4 the check is:

  if perl -we "exit ((v$bison_version ge v$bison_min_version) ? 0 : 1)"; then
    AC_MSG_RESULT([yes])
  else    
    AC_MSG_ERROR([no])
  fi

Which appears to always return a non-error return code (ie. exit(0)) for cases
where bison_version == "bison"

$ perl -we 'exit (("vbison" ge "v2.4.1") ? 0 : 1)'; echo $?
0
