Provide more overrides for make

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.
