* elfxx-mips.c (mips_got_info): Add a "reloc_only_gotno" field.
	(mips_elf_got_section): Delete.
	(mips_elf_sort_hash_table): Use g->reloc_only_gotno to decide
	how many reloc-only entries there are.
	(mips_elf_count_got_symbols): Adjust g->reloc_only_gotno as
	well as g->global_gotno.
	(mips_elf_make_got_per_bfd): Initialize reloc_only_gotno.
	(mips_elf_multi_got): Likewise.  Use gg->reloc_only_gotno
	rather than gg->assigned_gotno to store the number of
	reloc-only GOT entries.
	(mips_elf_create_got_section): Remove the MAYBE_EXCLUDE parameter.
	Initialize reloc_only_gotno.
	(mips_elf_calculate_relocation): Check htab->got_info instead of
	dynobj when deciding whether to call mips_elf_adjust_gp,
	(_bfd_mips_elf_create_dynamic_sections): Adjust the call
	to mips_elf_create_got_section.
	(mips_elf_record_relocs): Likewise.  Remove redundant
	"dynobj == NULL" code.  Do not use mips_elf_create_got_section
	or mips_elf_record_global_got_symbol for R_MIPS_32, R_MIPS_REL32
	and R_MIPS_64; limit global_got_area to GGA_RELOC_ONLY instead.
	(_bfd_mips_elf_finish_dynamic_symbol): Use htab->sgot instead
	of mips_elf_got_section.
	(_bfd_mips_vxworks_finish_dynamic_symbol): Likewise.
	(_bfd_mips_elf_finish_dynamic_sections): Likewise.
	Move the initial assignment of G to the block that uses it;
	it is used for an unrelated purpose later.

ld/testsuite/
	* ld-mips-elf/tls-hidden4.got, ld-mips-elf/tls-hidden4.r: We have
	removed an unused GOT entry that was allocated for the R_MIPS_32
	relocation against "undef", so adjust addresses down by 4 bytes.
	* ld-mips-elf/got-dump-1.d, ld-mips-elf/got-dump-2.d: We have
	changed the order of the GOT entries so that reloc-only ones
	come last.  "undef" is only referred to by dynamic relocations,
	so it now comes after "glob".
	* ld-mips-elf/mips16-pic-2.dd, ld-mips-elf/mips16-pic-2.gd,
	ld-mips-elf/mips16-pic-2.nd, ld-mips-elf/mips16-pic-2.rd: We have
	removed two unused local GOT entries that were originally created
	as global entries for the hidden symbols "used2" and "used3".
	"used4" and "used5" are only referred to by relocations, so they
	now come after "used6" and "used7".
