Python: clean up. config/Makefile and pyconfig are not needed anymore

- and really use our :host python to build target
- TODO fix target sysconfigdata with hostpython
  to make distutils happy

-Change the location of pyconfig.h
-
-The Python interpreter has a really strange behaviour: at *runtime*,
-it reads a Makefile and a header file named pyconfig.h to get some
-information about the configuration.
-
-The Makefile is located in usr/lib/python2.7/config, which is fine
-since this location is kept on the target.
-
-However, by default, the pyconfig.h is installed in
-usr/include/python2.7, but we completely remove the usr/include
-directory for the target. Since making an exception just for
-pyconfig.h is annoying, this patch also installs pyconfig.h to
-usr/lib/python2.7/config, and modifies the sysconfig module so that it
-looks in this location instead of usr/include.
-
-The pyconfig.h is still kept in usr/include/python2.7, because it is
-needed in the $(STAGING_DIR) when building third-party Python
-extensions that contain C code.
