Well, it kinda is:  scons running in the windows context to run commands
which are running in the linux context.  But yeah, it's not the
classical case, which I don't know how to fix or I would have done it
for IoTivity (of course I knew much much less about scons then!).

But I think this was really the crux of it: if it's Windows scons,
everything it finds is going to be in the Windows filesystem, then you
try to run actions which are going to need tools in the Linux container
- and last I knew Microsoft still said there wasn't support for Windows
commands looking at files inside the Linux environment (although it
works the other direction).

So scons will have detected all the wrong stuff.
