+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.

+Second patch to bring cross-compilation support to python build-system.
+
+Allow the libraries detection routine to look for headers and libs in
+other directories than /usr/include or /usr/lib through the env variables
+PYTHON_MODULES_INCLUDE and PYTHON_MODULES_LIB.
+
+We can then use it to look for libraries in the buildroot staging directory.

+Support some customisation on python compilation.
+
+With this patch, we can now remove some modules introducing external
+dependencies from the compilation, thus removing these irrelevant in most
+cases dependencies (ie. openssl, ncurses, etc).
+
+This modules can be removed by listing them in the PYTHON_DISABLE_MODULES
+environment variable.

+This patch purpose is to allow not to save the generated python bytecode in
+a file for later use through the PYTHON_DONTCOMPILE environment variable.
+
+I do not see the use of it, because you can choose if you want but it seems
+somewhat related to gentoo.
+
+Maybe useful when the generated rootfs is mounted on read-only on the target.
