The subfeature is called flavor.

What is the path component for the toolset? It should be
gcc-mingw-nnn. Otherwise the detection for mingw isn't working.
Also, I recall that there used to be problems if you have both
mingw and non-mingw versions of gcc. I don't remember whether
that was ever fixed.
