* elf32-mips.c: Extensive additions to do relocations and to 

handle MIPS specific sections.
	* libelf.h (elf_backend_data): Pass fourth argument to
	elf_backend_section_from_bfd_section to permit it to control the
	section index to use.
	(elf_obj_tdata): Add gp and gp_size fields.
	(elf_gp, elf_gp_size): New accessor macros.
	* elfcode.h: Removed a number of unused local variables.
	(elf_fake_sections): Clear section header before calling
	elf_backend_fake_sections, not after.
	(prep_headers): Return true at end.
	(elf_section_from_bfd_section): Pass retval argument to
	elf_backend_section_from_bfd_section.
	* elf32-hppa.c (elf32_hppa_backend_section_from_bfd_section):
	Accept and ignore new retval argument.
	* bfd.c: Include libelf.h.
	(bfd_set_gp_size): Handle ELF targets.
	* Makefile.in (bfd.o): Depends upon libelf.h.
	(elf32-mips.o): Depends upon $(INCDIR)/elf/mips.h.
