	* elfxx-mips.c (mips_elf_link_hash_table): Add function_stub_size.
	(STUB_ORI): New macro.
	(STUB_LI16U): Fix formatting.
	(MIPS_FUNCTION_STUB_SIZE): Delete.
	(MIPS_FUNCTION_STUB_MAX_SIZE): Likewise.
	(MIPS_FUNCTION_STUB_NORMAL_SIZE): New macro.
	(MIPS_FUNCTION_STUB_BIG_SIZE): Likewise.
	(_bfd_mips_elf_adjust_dynamic_symbol): Use htab->function_stub_size
	instead of MIPS_FUNCTION_STUB_SIZE.
	(count_section_dynsyms): New function, split out from
	_bfd_mips_elf_final_link.
	(_bfd_mips_elf_always_size_sections): Get a worst-case estimate
	of the number of dynamic symbols needed and use it to set up
	function_stub_size.  Use function_stub_size rather than
	MIPS_FUNCTION_STUB_SIZE to determine the size of the stub section.
	Use 16-byte stubs for 0x10000 dynamic symbols.
	(_bfd_mips_elf_size_dynamic_sections): Use htab->function_stub_size
	instead of MIPS_FUNCTION_STUB_SIZE.  Fix formatting.
	(_bfd_mips_elf_finish_dynamic_symbol): Likewise.  Change the
	size of the stub buffer from MIPS_FUNCTION_STUB_MAX_SIZE to
	MIPS_FUNCTION_STUB_BIG_SIZE.  Tweak the check for unhandled dynindxes.
	Use MIPS_FUNCTION_STUB_BIG_SIZE rather than a hard-coded 20.
	Use STUB_ORI rather than STUB_LI16U for big stubs.
	(_bfd_mips_elf_link_hash_table_create): Initialize function_stub_size.
	(_bfd_mips_elf_final_link): Use count_section_dynsyms.
