I do something like that.  I think to get it to have the exact structure
you want, you'd have to change some of the internals of boost.build.

    import feature : feature ;

    feature variety : A B C : optional composite link-incompatible ;
    feature.compose <variety>A : <define>VARIETY_A ;
    feature.compose <variety>B : <define>VARIETY_B ;
    feature.compose <variety>C : <define>VARIETY_C ;

You'd end up with something like bin/gcc/debug/variety-a,
bin/gcc/release/variety-b, etc, though, instead of your example tree.
