2012-08-01  James Lemke  <jwlemke@codesourcery.com>

	* gas/dwarf2dbg.c (out_set_addr): Allow for non-constant value of
	DWARF2_LINE_MIN_INSN_LENGTH
	* gas/config/tc-ppc.c (ppc_dwarf2_line_min_insn_length): Declare
	and initialize.
	(md_apply_fix): Branch addr can be a multiple of 2 or 4.
	* gas/config/tc-ppc.h (DWARF2_LINE_MIN_INSN_LENGTH): Now a
	variable reference.
