I don't think this can work in the cross-compilation case, though
(or the entire setup.py part of it can't really work). It uses the
target's python binary to run setup.py, compiles the modules, and then
tries to load them. In a cross-compilation case, you can't run the
target python binary, and even if you use a host python instead, you
can't load the target extension modules (unless the "cross" compilation
is for the same microprocessor and operating system - a case I'm not
very much interested in).
