* objcopy.c (copy_file): Accept corefiles (format bfd_core).
        (copy_object): Don't set the start address or flags of a core file.
        (copy_section): Don't relocate a core file.  Don't copy contents
        if the input section has the contents flag set, but the output
        section does not (which happens with the fake 'note' pseudo-
        sections that BFD creates for corefiles).
