commit 935ab8179287f3b7aefdbe3829110d369be1a5c8
Author: Joseph Myers <joseph@codesourcery.com>

    Fix resolver bind, getsockname namespace (bug 17733).
    
    On Linux architectures using socketcall, the resolver ends up bringing
    in strong symbols for bind and getsockname, which are not in
    POSIX.1-1996.  This causes linknamespace test failures:
    
    FAIL: conform/POSIX/pthread.h/linknamespace
    FAIL: conform/POSIX/sched.h/linknamespace
    FAIL: conform/POSIX/time.h/linknamespace
    
    These functions are defined as strong symbols with __bind and
    __getsockname as weak aliases.  This patch switches this to the other
    way round by removing the NO_WEAK_ALIAS definitions and so letting the
    default case in socket.S act; I see no reason for the existing
    arrangements.
    
    Tested for x86 (testsuite, and that disassembly of installed shared
    libraries is unchanged by the patch).

    	* sysdeps/unix/sysv/linux/getsockname.S (NO_WEAK_ALIAS): Do not
    	define.
    	(__getsockname): Do not define as weak alias.
