Well, it seems buildroot solves this main problem by building another
version of python and pygen that run on the build machine, and hacks
the Makefile to run setup.py with these instead of whatever happens to
be sitting in /usr/bin.

Thus the modules that do get built seem to work just fine, but
setup.py itself ignores all this careful hackery when determining what
modules to build and configuring distutils to search for system
libraries in various dynamically-discovered paths.
