So, you want Boost.Build to get Boost root directory based on the path where
Boost.Build itself is found.

That can be made to work, but:

1. It will break if your users happen to use system-wide Boost.Build. FWIW,
there's already Boost.Build package for Debian, and users might install it
from source themselfs too.

2. This will work only for Boost, but not for any third-party libraries.

The general solution seems to either set some environment variable what will
be read by Jamroot, or hardcode paths in Jamroot and modify Jamroot when you
move the source to a different machine.
