x86: Fix missing __wmemcmp def for disable-multiarch build 

commit 8804157ad9

    x86: Optimize memcmp SSE2 in memcmp.S

Only defined wmemcmp and missed __wmemcmp. This commit fixes that by
defining __wmemcmp and setting wmemcmp as a weak alias to __wmemcmp.

Both multiarch and disable-multiarch builds succeed and full xchecks
pass.
