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.
