Fix powerpc64 segfault caused by zero r_symndx relocs.

Fixes a segfault in ppc64_elf_tls_optimize found when testing
R_PPC64_ENTRY, and potential for trouble in other places found by
code inspection.

* elf64-ppc.c (ppc64_elf_tls_optimize): Don't segfault on NULL
symbol section or output section.
(ppc64_elf_edit_toc): Similarly for ld -R objects.
(ppc64_elf_size_stubs): Likewise.
