commit 293d9a41805b1eeb440a2c59a717b332cd9c2384
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Nov 12 22:35:12 2014 +0000

    Fix x86_64 rawmemchr namespace (bug 17572).
    
    rawmemchr is not an ISO C function, but __rawmemchr is called from ISO
    C functions, so rawmemchr should be a weak alias.  On most
    architecture it is, but x86_64 defines the function as rawmemchr with
    __rawmemchr as a strong alias.  This patch makes x86_64 follow the
    same arrangements as other architectures.
    
    Tested for x86_64 (testsuite, and that disassembly of installed shared
    libraries is unchanged by the patch).
    
    	[BZ #17572]
    	* sysdeps/x86_64/rawmemchr.S (rawmemchr): Rename to __rawmemchr
    	and define as weak alias of __rawmemchr.
    	(__rawmemchr): Do not define as strong alias of rawmemchr.
