+Add cross-compilation support in the python Makefile and setup.py since
+python has no such support.
+
+The main point here is to first build a python interpreter to run on the
+host, and then use it to compile the target python.
+
+We also remove some error-generating code that is irrelevant in our
+situation, such as checking if we can import a cross-compiled module.
