Suppose one has exactly that same use case as you - sources on shared
folder. But, its not only Boost, but also an app using Boost. If I build
that app and specify --build-dir then I want build products of app and
Boost to be separate - in part because there might be naming conflicts
otherwise and in part so that building another app using Boost do not
rebuild Boost from scratch. These considerations do not apply when
build-dir is specified in Jamroot - because there, it is relative to source
directory and therefore disambiguated naturally.

Regarding tools that override build dir - that is bad, I'd be happy to help
that fixed.
