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.
