* elf-bfd.h (elf_backend_data): Remove use_rela_p. Add

	may_use_rel_p, may_use_rela_p, default_use_rela_p.
	(bfd_elf_section_data): Add use_rela_p.
	* elf.c (bfd_section_from_shdr): Set use_rela_p appropriately.
	(_bfd_elf_new_section_hook): Likewise.
	(elf_fake_sections): Use may_use_rela_p, etc., instead of
	use_rela_p.
	(_bfd_elf_copy_private_section_data): Copy use_rela_p.
	* elfcode.h (write_relocs): Determine whether or not use rela
	relocs based on the relocation section header.
	* elflink.c (_bfd_elf_create_dynamic_sections): Use default_use_rela_p
	instead of use_rela_p.
	* elfxx-target.h (elf_backend_may_use_relp): New macro.
	(elf_backend_may_use_rela_p): Likewise.
	(elf_backend_default_use_rela_p): Likewise.
	(elfNN_bed): Use them.
