Have found some resources, but still don't really understand, how to use it in BR:

http://whatschrisdoing.com/blog/2009/10/16/cross-compiling-python-extensions/
http://pypi.python.org/pypi/distutilscross

I've installed distutilscross and exported the needed environment variables, but setup.py still doesn't take specified crosscompiler while checking for headers (renamed output/host/usr/bin/arm-none-linux-gnueabi-gcc and setup.py didn't complain). Another thing that I don't really understand, how should distutilscross help if I don't include this package?
