Hide ppc64 .TOC. from --export-dynamic
I can't see any good reason why anyone would want a dynamic .TOC., so
hide it in a way that is respected by _bfd_elf_export_symbol. This
also fixes an abort in relocate_section on not finding sreloc for .TOC.
* elf64-ppc.c (ppc64_elf_func_desc_adjust): Make .TOC. defined and
hidden.
(ppc64_elf_set_toc): Adjust.
