[ 001/120] mn10300: only add -mmem-funcs to KBUILD_CFLAGS if gcc supports it

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>

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.
