x86: Add missing IS_IN (libc) check to strcspn-sse4.c
Was missing to for the multiarch build rtld-strcspn-sse4.os was
being built and exporting symbols:
build/glibc/string/rtld-strcspn-sse4.os:
U ___m128i_shift_right
U __strcspn_generic
0000000000000000 T __strcspn_sse42
U strlen
build/glibc/string/rtld-varshift.os:
0000000000000000 R ___m128i_shift_right
Introduced in:
commit 06e51c8f3de38761f8855700841bc49cf495c8c0
Author: H.J. Lu <hongjiu.lu@intel.com>
Date: Fri Jul 3 02:48:56 2009 -0700
Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64.
