Noah Goldstein	c72a1a062a	x86: Fix missing __wmemcmp def for disable-multiarch build ... commit 8804157ad9 Author: Noah Goldstein <goldstein.w.n@gmail.com> Date: Fri Apr 15 12:27:59 2022 -0500 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. Reviewed-by: H.J.
