remove conditional compilation of HAVE_AS_LEB128 code

gcc/ChangeLog:

2016-08-20  Trevor Saunders  <tbsaunde+gcc@tbsaunde.org>

	* acinclude.m4 (gcc_GAS_CHECK_FEATURE): Support doing an action
	if the feature isn't available.
	* configure: Regenerate.
	* configure.ac: define HAVE_AS_LEB128 to 0 when not available.
	* dwarf2asm.c (dw2_asm_output_data_uleb128): Always compile code
	for HAVE_AS_LEB128.
	(dw2_asm_output_data_sleb128): Likewise.
	(dw2_asm_output_delta_uleb128): Likewise.
	(dw2_asm_output_delta_sleb128): Likewise.
	* except.c (output_one_function_exception_table): Likewise.
	(dw2_size_of_call_site_table): Likewise.
	(sjlj_size_of_call_site_table): Likewise.
	* dwarf2out.c (output_loc_list): Likewise.
	(output_rnglists): Likewise.
