+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.
