* elf32-ppc.c (elf_linker_section_pointers_t): Remove 

written_address_p.
	(ppc_elf_create_linker_section): Don't try to reuse existing section.
	(elf_create_pointer_linker_section): Delete info parm.  Don't make
	h dynamic.  Don't set written_address_p.
	(ppc_elf_check_relocs): Adjust ppc_elf_create_linker_section calls.
	(bfd_put_ptr): Delete.
	(elf_finish_pointer_linker_section): Remove output_bfd and info parms.
	Always write section contents.  Assert global sym is def_regular.
	Use offset bottom bit as a written flag.
	(ppc_elf_relocate_section): Adjust elf_finish_pointer_linker_section
	calls.
