Additional Build functions:
- breakfast:       Setup the build environment, but only list
                   devices we support.
- cout:            Changes directory to out.
- mka:             Builds using SCHED_BATCH on all processors.
- pushboot:        Push a file from your OUT dir to your phone and
                   reboots it, using absolute path.
- repopick:        Utility to fetch changes from Gerrit.
