[PATCH v1] x86: Remove unneeded rtld-wmemcmp

[Noah Goldstein <goldstein.w.n@gmail.com>]

wmemcmp isn't used by the dynamic loader so their no need to add an
RTLD stub for it.

Tested with and without multiarch on x86_64 for ISA levels:
{generic, x86-64-v2, x86-64-v3, x86-64-v4}

And m32 with and without multiarch.
