I suppose you could run the config step (using the host's compiler),
then go and fix up the generated config files in the build/ directory.
Hmm, looks to me if you run 'python setup.py build_src', then go poke
around in build/src.<something>, you should find a numpy/
__config__.py, numpy/distutils/__config__.py (which look to be the
same file, for some reason), and a numpy/core/config.h
I *think* that's all you you'd have to fiddle. Then you should be
able to build the modules by setting CC to your cross compiler, and
doing 'python build_ext build_py' (Almost; looks like one config test
is done in build_ext).
Hope that helps; patches to make this cleaner are welcome.
