Subject: [PATCH] python: Resolve intermediate staging issues
When cross compiling python, we used to need to install the Makefile, pyconfig.h
and the python library to their final location before being able to compile the
rest of python. This change allows us to point python at its own source when
building, avoiding a variety of sysroot staging issues and simplifying the main
python recipe.
