PR24968, make objcopy use output ELF arch if -B not given
This should make objcopy -B redundant for the common case of producing
ELF output where the -O target defaults to the desired arch:mach.
PR 24968
* objcopy.c (copy_object): For ELF output and non-ELF input without
arch, take arch from output file if not given by -B. Don't
bfd_get_arch_info when we already have iarch.
