The system supports a cache of prebuilt objects in the form of the
sstate data to accelerate build times if nothing changes. It doesn't
directly support using prebuilt packages directly though as its a much
harder problem to solve than you first realise.

A an example, given a package feed, its very hard to work out library
provision within that package feed or dependency naming.
