	* elfxx-mips.c (mips_elf_local_pic_function_p): Return true when
	H is a MIPS16 function with a kept 32-bit stub. Update comments.
	(mips_elf_get_la25_target): New function.
	(mips_elf_add_la25_intro): Change to use mips_elf_get_la25_target().
	(mips_elf_add_la25_stub): Move compute of use_trampoline_p down,
	change to use mips_elf_get_la25_target().
	(mips_elf_relocation_needs_la25_stub): Add target_is_16_bit_code_p
	parameter, add switch case for R_MIPS16_26.
	(mips_elf_calculate_relocation): Redirect relocation to point to the
	LA25 stub if it exists, instead of the MIPS16 stub. Update arguments
	of call to mips_elf_relocation_needs_la25_stub(), don't use la25 stub
	for mips16->mips16 calls.
	(_bfd_mips_elf_check_relocs): Update arguments of call to
	mips_elf_relocation_needs_la25_stub().
	(mips_elf_create_la25_stub): Change to use mips_elf_get_la25_target().
