objdump --no-addresses

I find this useful when needing to compare compiler output, where the
address of the instruction and the value of symbols results in
unwanted differences.

	* objdump.c (no_addresses): New static var.
	(usage): Print help for --no-addresses.
	(long_options): Add --no-addresses entry.
	(objdump_print_addr_with_sym, objdump_print_addr): Omit symbol address.
	(disassemble_bytes): Don't print current line address, or reloc
	address.
	* doc/binutils.texi: Document objdump --no-addresses.

+and relocation offsets.

 @item --prefix-addresses
 When disassembling, print the complete address on each line.  This is
 the older disassembly format.
