commit f9dffbf0863b9010a5eece87bd6b36e38c09ffb0

    Default powerpc64 to --plt-thread-safe for Go
    
    Go is multi-threaded, so use thread-safe plt stubs.  __go_go doesn't
    actually start threads, but is a convenient libgo function with a
    reasonably unique name that is called by all Go executables.  (Threads
    are started by a static function of libgo, runtime_newosproc, called
    by a whole lot of global functions, including runtime_starttheworld
    and runtime_main.)
    
    bfd/
    	* elf64-ppc.c (ppc64_elf_size_stubs): Add __go_go to thread_starters.
    gold/
    	* powerpc.cc (Target_powerpc::do_relax): Add __go_go to thread_starters.
