* elf-bfd.h (struct elf_backend_data): Add gc_keep. Remove param
names from others.
(_bfd_elf_gc_keep): Declare.
* elfxx-target.h (elf_backend_gc_keep): Define.
(elfNN_bed): Init new field.
* elflink.c (_bfd_elf_gc_keep): New function.
(bfd_elf_gc_sections): Call gc_keep.
* elf64-ppc.c (elf_backend_gc_keep): Define.
(struct _ppc64_elf_section_data): Move .opd related fields to
a struct so they don't occupy the same storage. Adjust accesses
throughout file.
(ppc64_elf_gc_keep): New function, split out from..
(ppc64_elf_gc_mark_hook): ..here. Don't call _bfd_elf_gc_mark
to mark .opd section, just set gc_mark.
(ppc64_elf_edit_opd): Remove no_opd_opt parm. Don't set opd->adjust
unless we are changing .opd. Test non-NULL opd->adjust at all
accesses throughout file.
* elf64-ppc.h (ppc64_elf_edit_opd): Update prototype.

* ldlang.c (lang_gc_sections): Move code to set SEC_KEEP on entry
syms to _bfd_elf_gc_keep.
* emultempl/ppc64elf.em (ppc_before_allocation): Don't call
ppc64_elf_edit_opd if no_opd_opt.
