    objcopy --strip-symbols and similar with file arg
    
    If something like --strip-symbols /dev/urandom is passed to objcopy
    we get a -1 return from get_file_size which isn't checked.  Things go
    downhill from there.
    
            * objcopy.c (add_specific_symbols): Fail on negative return
            from get_file_size.
