[Buildroot] [git commit branch/next] pkg-python: no longer use distutilscross for setuptools

commit: http://git.buildroot.net/buildroot/commit/?id=c7bf337ec56c4753d58de3e4c16f3f74e17d5001
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Thanks to the bump of Python 2.x, distutilscross is no longer needed
to achieve cross-compilation for setuptools packages. The host Python
2.x interpreter can be tricked into using the target compiler thanks
to pointing it to a different sysconfigdata module, which is achieved
using PYTHON_PATH.
