GCC doesn't attempt to distinguish. It doesn't look inside the name in
the MAKE environment variable: just passes it to 'pex_one' (the
exec/spawn wrapper in libiberty) to find and execute it. If the
makefile is constructed to be system agnostic, maybe this could work.
I think the real situation is that "native" Make is not supported.
