glibc build requires GNU bison >= 2.7 but Apple ships bison 2.3. If we
provide an override for GNU bison it should be possible to use a version
from homebrew.

glibc's configure script looks for make in the following order:
gnumake gmake make
but crosstool-ng has an override only for make. So glibc picks up
gnumake from system and fails to proceed with the build because system
make is very old.
It'd more reliable if we also override gnumake and gmake.
