More fun with R_PPC64_NONE found in .opd.  Fixed by the
allocate_dynrelocs and ppc64_elf_size_dynamic_sections changes, and
since we are doing ifunc, opd and SYMBOL_REFERENCES_LOCAL tests later,
don't duplicate that work in check_relocs.

* elf64-ppc.c (ppc64_elf_check_relocs): Remove opd and ifunc
conditions for rel_count.
(dec_dynrel_count): Likewise.
(allocate_dynrelocs): Test for opd and ifunc when allocating
relative relocs.
(ppc64_elf_size_dynamic_sections): Likewise.
