    Allow elfcopy to convert between two non-ELF formats
    
    If the output object is not an ELF file, choose an arbitrary
    ELF format for the intermediate file. srec, ihex and binary
    formats are independent of class, endianness and machine
    type so these choices do not affect the output.
