libffi: fix native build being not portable

Without `--with-gcc-arch=generic` libffi looks up the cpuid to automatically determine
which mtune/march to use. This makes the native sstate-cache unuseable since it's
possible to have a newer cpu building the recipe and the library being pulled from
another older cpu which doesn't have the instruction.
