	* elfxx-mips.c (mips_elf_link_hash_table): Add an "sstubs" field.
	(_bfd_mips_elf_create_dynamic_sections): Use it to cache the stubs
	section.  Don't check whether the section already exists.
	(_bfd_mips_elf_adjust_dynamic_symbol): Use htab->sstubs.
	(_bfd_mips_elf_finish_dynamic_symbol): Likewise.
	(_bfd_mips_elf_finish_dynamic_sections): Likewise.
	(_bfd_mips_elf_size_dynamic_sections): Likewise.  Don't add the
	dummy stub to an empty section.
	(_bfd_mips_elf_link_hash_table_create): Initialize the "sstubs" field.

	* ld-mips-elf/tls-hidden3.ld: Remove the unused .MIPS.stubs section.
	Keep the text start address the same.
	* ld-mips-elf/tls-multi-got-1.got: We have removed a .MIPS.stubs
	section that contained only a 16-byte dummy stub.  Subtract 16
	from addresses to account for the change.
	* ld-mips-elf/tls-multi-got-1.r: Likewise.  Adjust MIPS_UNREFEXTNO
	to account the removed section symbol.
	* ld-mips-elf/tlsdyn-o32-1.d: We have deleted a .MIPS.stubs
	section that contained only a 16-byte dummy stub.  Remove it
	from the disassembly.
	* ld-mips-elf/tlsdyn-o32-2.d: Likewise.
	* ld-mips-elf/tlsdyn-o32-3.d: Likewise.
	* ld-mips-elf/tlsdyn-o32.d: Likewise.
