	* config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
	branch with an instruction that uses $at, in case the branch is
	later expanded.
	(macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
	(md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
	to make it pcrel_offset.
	(tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
	reloc->address; another gruesome hack to get gas reloc handling to
	do the right thing.
