I did it that way because that is how the build system of the project I'm
working on does it. You are right that it would make more sense to have
independant features. I'll do it that way in the future.

A general cross-compliation feature in Boost.Build would probably cover
my needs. I'd prefer that someone more familiar than I with the Boost.Build
system design it, however :-}.
