	statements.
	(debug_arc_reloc): Handle symbols that are not from an input file.
	(arc_do_relocation): Remove excessive exclamation points.
	(elf_arc_relocate_section): Print an informative message if the
	relocation fails, even if debugging is not enabled.
	* arc-got.h: Fix formatting.  Fix printing of debug information.
	(new_got_entry_to_list): Use xmalloc.
	* config.bfd: use the big-endian arc vector as the default vector

	little endian mode.
