* elf-bfd.h (struct elf_link_hash_table): Add hgot field.

	* elf.c (_bfd_elf_link_hash_table_init): Initialize hgot field.
	* elflink.c (_bfd_elf_create_got_section): Store the
	_GLOBAL_OFFSET_TABLE_ hash table entry in the hgot field.
	* elf32-sparc.c (elf32_sparc_check_relocs): If the size of the
	global offset table goes over 0x1000, set the value of
	_GLOBAL_OFFSET_TABLE_ to 0x1000 into the section.
	(elf32_sparc_relocate_section): Subtract the offset of
	_GLOBAL_OFFSET_TABLE_ when handling GOT relocations.
