  From 3c877ea9f09913586f87064b7a2b9d2b49cb05aa Mon Sep 17 00:00:00 2001
  From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
  Date: Wed, 23 Dec 2015 11:48:44 +0100
  Subject: [PATCH] Add an option to disable lib2to3
  
  lib2to3 is a library to convert Python 2.x code to Python 3.x. As
  such, it is probably not very useful on embedded system targets.
