I found the best way to deal with building python modules is the following:

PYINC=`python -c "import distutils.sysconfig; print 
distutils.sysconfig.get_python_inc()"`
PYLIB=`python -c "import distutils.sysconfg; print 
distutils.sysconfig.get_python_lib(prefix='')"`
CFLAGS += -I$(PYINC)

And then to use $(DESTDIR)$(prefix)/$(PYLIB) for the install path of the 
module.  You have to write your own rules to build the shared object but 
at least you don't have these cross-compiling issues.
This is how the python bindings are built in libxen.
