Initial proof of concept.

Currently, if you run this on a Linux box as an unprivileged user:

  $ ./bootstrap armv7 /some/scratch/directory

you will end up with, completely from source:

    rootfs-armv7l-adelie-linux-musleabihf-preimage.tgz

which is an armv7-native rootfs with all the tools that you need
to build our distribution. (Substitute your favorite target).

Work that remains to be done involves fixing "bootstrap.sh" in the
packages.git repository, then plumbing that back into this project
so that the complete process can be automated.
