The problem is that Boost has it's own project-root.jam, and so does not
inherit any properties of any projects. In fact, it inherits properties --
but from user-config.jam, not any your files.

There's really no mechanism to apply any properties to a project that has
Jamroot file (or in case of older projects, project-root.jam).

I tend to think that overriding --build-dir inside boost-build.jam for your
project is the most straight-forward solution.
