Message 164406 - Python tracker

Patch looks okay as it contains no important changes to distutils, the compilers or any big part; it’s the sort of changes that have been accepted to fix Mac issue or support multiarch on Debian.  I would prefer safer names for environment variables though, for example PYTHON_BUILD_HOST_PLATFORM instead of just _HOST_PLATFORM (unless this is not specific to the Python build process but used by all cross-compiling builds).
