> would (which "gcc") work when cross compiling?

When cross-compiling the cross gcc is named target-gcc
(aarch64-linux-gnu-gcc for instance), so (which "gcc") would return the
native compiler, not the cross one.

Note that when using autoconf/autotools, cross-compilation is working
fine because we pass "--host=target" and it manages to find the native
and cross-compiler from that.

This issue only arises when raw Makefile are using hard-coded CC=gcc to
build stuff.

Thanks,

Mathieu
