Hi Guix team!

Here is the Boost Build system which became a stand alone project now.
It would be nice have a build system base on it, there are a number of
projects which are built with it. Boost package may be rewritten and
simplified as well.

I was not sure about the nameing becouse of
https://www.boost.org/build/doc/html/bbv2/faq/names.html
- boost-build
- b2
- bjam
- boost-b2

so I've stope on boost-b2 but it may be renamed to something more suitable.

> B2 makes it easy to build C++ projects, everywhere. B2 has been the primary build system for the Boost C++ Libraries for many years. The main development now lives here at BFG in order to grow the audience outside of Boost.
