Refactor the options handling in defaults.py to allow the --jobs option have varing specific parameters. The option supports 'none', 'max' and 'half' or a fraction to divide the number of CPUs or an integer value which is the number of jobs. The --no-smp has been removed. The host specific modules have been changed to set the number of CPUs in the defaults table. Fixed the --keep-going to clean up is --always-clean is provided even if the build has an error.
