the section contents.
	* config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
	symbol table and values right.
	* config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
	with $L is local.
	* config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
	by the section vma.

	* config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
	z8k-opc.h, not z8k.h.
