commit 1818483b15d22016b0eae41d37ee91cc87b37510
Author: Andreas Schwab <schwab@suse.de>
Date:   Wed Dec 18 11:53:27 2013 +1000

    Remove use of SSE4.2 functions for strstr on i686
    
    The SSE4.2 have been removed from x86_64 by commit 584b18eb.  This patch
    fixes the build on i686, which attempts to use the removed files.
