Because python cannot be built using Boost.Build, and because for Qt,
the official build system is not Boost.Build. For Boost,  we have
the luxury of being able to create whatever we want. Also, both python
and qt have additional functionality, it's not just linking to libraries.

You can have 'use-project' in user-config.jam. Remember that user-config.jam
is essentially a project.

For a prebuilt libs that are not created with Boost.Build, we'd have to
use the current approach of duplicate some-other-lib.jam into the 'tools'
directory -- as we cannot expected $prefix/share/whatever/Jamroot 
will exist.
