[Buildroot] [PATCHv1 07/26] pkg-python: no longer use distutilscross for setuptools

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.
