Short answer - you cannot control it. The directory name is constructed 
from the actual feature set is used. By default ('bjam --v2') debug 
variant is built. That is why you get bin/debug. But a user may pass 
more features and the build directory will become /bin/debug/foo/bar.

IMO it is a bad idea. BB expects that the current directory will not be 
changed and all filenames used by invoked tools will include path:

actions
{
tool foo/bar/somefile.ext
}

But not

actions
{
cd foo/bar
tool somefile.ext
cd ../..
}

You can try to generate all possible names from single file name and 
establish dependencies on all of them.
