mk: make it completely generic

commands now fed from a file, include/common.sh
which in turn also includes other lib files

this makes mk completely generic, and means
that changes will now be completely in sync
with cbmk, ensuring a lack of merge conflicts,
though the file was already pretty small anyway.
