x86, build: Don't get confused by local symbols
arch/x86/crypto/sha1_avx2_x86_64_asm.S introduced _end as a local
symbol, which broke the build under certain circumstances. Although
the wisdom of _end as a local symbol can definitely be questioned, the
build should not break for that reason.
Thus, filter the output of nm to only get global symbols of
appropriate type.
