Enhance config to handle MACHINEs with multiple architectures:
- Passing -m to config will now print the MACHINE and MACHINE_ARCH
given in the passed kernel configuration file and then exit.
- If an option is defined in options.MACHINE with the same name as the
architecture of the kernel being configured, that option will be
considered set. This allows conditional compilation based on CPU
architecture.
Config version is now 600010.
