* elf-bfd.h: Add prototypes for _bfd_elfcore_make_pseudosection

	and _bfd_elfcore_strndup.
	(struct elf_backend_data): Add elf_backend_grok_prstatus
	and elf_backend_grok_psinfo.
	* elf.c (_bfd_elfcore_make_pseudosection): New function.
	(elfcore_grok_prstatus): Use it.
	(elfcore_make_note_pseudosection): Likewise.
	(elfcore_strndup):  Rename to...
	(_bfd_elfcore_strndup): Here, and make global.
	(elfcore_grok_psinfo): Use _bfd_elfcore_strndup.
	(elfcore_grok_note): Call elf_backend_grok_prstatus
	and elf_backend_grok_psinfo if available.
	* elf32-mips.c (_bfd_elf32_mips_grok_prstatus): New function.
	(_bfd_elf32_mips_grok_psinfo): New function.
	(elf_backend_grok_prstatus): Define.
	(elf_backend_grok_psinfo): Define.
	* elfxx-target.h (elf_backend_grok_prstatus): Default to NULL.
	(elf_backend_grok_psinfo): Likewise.
	(elfNN_bed): Include elf_backend_grok_prstatus and
	elf_backend_grok_psinfo.
