PR25031, nm reports wrong address on 32bit

Browse Source 
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.
