Partial hack to cross-compile lang/python27.  XXX unfinished

XXX We really need a tool dependency on Python, and some patches to
make the Python build system use the native Python.  See openwrt's
Python package for more information, although I think we can do it
more easily because we already have infrastructure for building
native packages.
