mn10300: only add -mmem-funcs to KBUILD_CFLAGS if gcc supports it

commit 9957423f035c2071f6d1c5d2f095cdafbeb25ad7 upstream.

It seems the current (gcc 4.6.3) no longer provides this so make it
conditional.

As reported by Tony before, the mn10300 architecture cross-compiles with
gcc-4.6.3 if -mmem-funcs is not added to KBUILD_CFLAGS.
