Force usage of either byacc or yacc or older-not-in-tree Bison (< 3.7); it's not enough to just depend on these because we can't really be sure what kbuild will try to use, especially if a newer Bison is installed (it'll just try to use it and die). We choose byacc > yacc > older Bison but allow the user to override it via the environment if they wish. Right now, manual intervention seems to be required for people to install this if, as is likely, users have modern Bison installed (they'd need to unmerge (ugh!) Bison and then install byacc or yacc & hope the build system picks it up).
