	* elfxx-mips.c (mips_elf_link_hash_entry): Add got_only_for_calls.
	(mips_elf_link_hash_newfunc): Initialize it.
	(mips_elf_record_global_got_symbol): Add a for_call parameter.
	(mips_elf_count_got_symbols): Check SYMBOL_CALLS_LOCAL rather
	than SYMBOL_REFERENCES_LOCAL if the GOT entry is only used for calls.
	Try to remove .got entries in favour of .got.plt entries on VxWorks.
	(_bfd_mips_elf_check_relocs): Do not try to avoid allocating
	a global GOT entry for VxWorks calls.  Update uses of
	mips_elf_record_global_got_symbol.
	(allocate_dynrelocs): Set got_only_for_calls to false if the GOT
	entry is used for dynamic relocations.
