linker relaxation.
	(dwarf2_gen_line_info): Generate real, local, labels for line
	numbers.
	(dwarf2dbg_convert_frag): Do not finalize the computation of the
	frag's symbol value when linker relaxation is enabled.
	(ADDR_DELTA_LIMIT): Define.
	(size_fixed_inc_line_addr): Use ADDR_DELTA_LIMIT.
	(emit_fixed_inc_line_addr): Likewise.
	* write.c (fixup_segment): If the subtraction of two symbols
	cannot be resolved but is valid, then prevent bogus range warnings
	by pre-biasing add_number.
	* config/tc-h8300.h (DWARF2_USE_FIXED_ADVANCE_PC): Define to 0.

	* gas/lns/lns.exp: Use alternate lns-common test for targets
	enabling linker relaxation.
	* gas/lns/lns-big-delta.d: Allow for output from architectures
	with 32-bit addresses.
