commit: http://git.buildroot.net/buildroot/commit/?id=40281284ad5ab41fea4058d57c130cbae0fb9d70
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

distutils adds -L$LIBDIR (/usr/lib), breaking build of binary extensions.
Seen with netifaces, but other extensions may be affected as well.

I hope this talk will change the situation in the future: https://us.pycon.org/2012/schedule/presentation/11/.

I've tried to raise this issue in distutils mailing list, but no one answered: http://python.6.n6.nabble.com/RFC-real-cross-compiling-support-for-Distutils2-td4368968.html

Yes, let's hope so.

Thanks.

No, I haven't. I'm not the author of them (Thomas did - I think he based
them on patches in openwrt).
