Apparently according to @majnemer (please correct me if I'm wrong here) that it's a special case in gold -- so unless we teach gold to treat xray_instr_map sections as special, or find a way to make this an option you can provide as a flag then this seems to be the thing that works for now. I agree we could do better by changing the linkers to do the right thing, but that will take longer.
