This is far from obvious when reading the code at main(). Instead of making it call qdev_get_machine(), require the caller of parse_cpu_option() to provide the machine object. This makes the initialization dependency explicit at main(), and will let us move qdev_get_machine() to CONFIG_SOFTMMU in the future.
