[PATCH] i686: Add missing IS_IN (libc) guards to vectorized strcspn

Since commit d957c4d3fa48d685ff2726c605c988127ef99395 (i386: Compile
rtld-*.os with -mno-sse -mno-mmx -mfpmath=387), vector intrinsics can
no longer be used in, even if the compiled code never makes it
into the final link.  This commit adds the missing IS_IN (libc)
guard to the SSE 4.2 strcspn implementation, so that it can be used from in the future.

2017-06-14  Florian Weimer  <>

	* sysdeps/i386/i686/multiarch/strcspn-c.c: Add IS_IN (libc) guard.
	* sysdeps/i386/i686/multiarch/varshift.c: Likewise.
