PowerPC64 linking of --just-symbols objects (klibc)

With -mcmodel=medium we can't assume that a -R object doesn't use
toc-relative addressing if there's no toc.  Lots of things are
accessed via r2, not just the toc/got section.  Also, testing for
.opd is plain wrong for ELFv2.

	* elf64-ppc.c (ppc64_elf_link_just_syms): Remove .got check.
	Handle ELFv2.
