This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.
This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.
Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.
