    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 ld.so, even if the compiled code never makes it
    into the final ld.so link.  This commit adds the missing IS_IN (libc)
    guard to the SSE 4.2 strcspn implementation, so that it can be used from
    ld.so in the future.
    
    (cherry picked from commit 69052a3a95da37169a08f9e59b2cc1808312753c)
