+Add infrastructure to disable the build of certain extensions
+
+Some of the extensions part of the Python core have dependencies on
+external libraries (sqlite, tk, etc.) or are relatively big and not
+necessarly always useful (CJK codecs for example). By extensions, we
+mean part of Python modules that are written in C and therefore
+compiled to binary code.
+
+Therefore, we introduce a small infrastructure that allows to disable
+some of those extensions. This can be done inside the configure.in by
+adding values to the DISABLED_EXTENSIONS variable (which is a
+word-separated list of extensions).
+
+The implementation works as follow :
+
+ * configure.in defines a DISABLED_EXTENSIONS variable, which is
+   substituted (so that when Makefile.pre is generated from
+   Makefile.pre.in, the value of the variable is substituted). For
+   now, this DISABLED_EXTENSIONS variable is empty, later patches will
+   use it.
+
+ * Makefile.pre.in passes the DISABLED_EXTENSIONS value down to the
+   variables passed in the environment when calling the setup.py
+   script that actually builds and installs those extensions.
+
+ * setup.py is modified so that the existing "disabled_module_list" is
+   filled with those pre-disabled extensions listed in
+   DISABLED_EXTENSIONS.
+
+Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
+then extended by Thomas Petazzoni
+<thomas.petazzoni@free-electrons.com>.
