a) The python cross-compilation problems stem from the fact that python
facilities are being used to build your python-binding libraries.  I
don't see an easy way to tell those tools that they should be
cross-compiling. Setting CC and CFLAGS and the like is not enough; the
python tools need to realize that they must build using a python
installation that is not the installation that is being used to run the
build. 

Cross-compilation environments also tend to be fairly poor in
terms of the libraries that are present and my experience has been that
higher-level libraries and tools tend to be less cross-compilation
friendly.

b) I'm not assuming I can fix everything in one shot.

c) I can cross-compile vm-tools.
