With the ability to build targets for more than one arch, I will be
tempted to use syntax like this

buildman (powerpc & freescale) (arm & freescale) aarch64

buildman mpc85xx mpc83xx mpc86xx (arm & freescale) aarch64

buildman powerpc (arm & freescale) aarch64

I can see myself using these commands if they can be supported.

I use "git clean -xfqd" after checkout every commit to make sure I have a
clean working directory. Each commit can potentially add/remove a board.
