^^^^^^^^^^^^^^^^^^^
I'm going to let Rene handle this part, but it seems like a bug

Yes. Spaces are significant, so you need
    debug <threading>single/multi

Maybe you meant:

    <debug><threading>single/multi

which says that the debug build should be built in single- and multi-
threaded versions.

    debug <threading>single/multi

means that you should only build a debug build by default (this is
redundant, since that's the default anyway) in single and multithreaded
subvariants.
