* elf-bfd.h (elf_backend_data): Add a "rela_plts_and_copies_p" field.
	* elfxx-target.h (elf_backend_rela_plts_and_copies_p): New macro.
	(elfNN_bed): Use it.
	* elf.c (_bfd_elf_get_synthetic_symtab): Use rela_plts_and_copies_p
	instead of default_use_rela_p to choose between ".rel.plt" and
	".rela.plt".
	* elflink.c (_bfd_elf_create_dynamic_sections): Use
	rela_plts_and_copies_p instead of default_use_rela_p to choose
	between ".rel.plt" and ".rela.plt", and between ".rel.bss" and
	".rela.bss".
