PR25031, nm reports wrong address on 32bit
Using saved_format breaks when nm is presented with multiple object files, some 32-bit and some 64-bit. PR 25031 * nm.c (print_format_string): New. (get_print_format): Delete saved_format. Move earlier. (set_print_width): Call get_print_format. (print_value): Use print_format_string.
