commit 2300b5a1414ecb820aa042a30a08928cfcba620b
Author: Alan Modra <amodra@gmail.com>
Date:   Tue Oct 21 17:06:01 2014 +1030

    Add gcc-4.9 libgomp symbols requiring --plt-thread-safe for power7
    
    powerpc64 ld builds plt call stubs with a read barrier to provide
    thread safety on lazy plt updates, necessary on multi-threaded apps
    with power7 or later weakly ordered memory.  gcc-4.9 libgomp
    introduced more functions that could call pthread_create, which means
    we have more functions that if referenced in an executable should
    cause a default of --plt-thread-safe.
    
    	* elf64-ppc.c (ppc64_elf_size_stubs): Add gcc-4.9 libgomp functions
    	to thread_starter.
