+Add support in Python build system to specify host pgen
+
+Python needs a "pgen" program to build itself. Unfortunately, the
+Python build system assumes that it can use the pgen program it has
+just built to build itself. Obviously, this cannot work in
+cross-compilation mode since the pgen program have been built for the
+target.
+
+Therefore, this patch adds support in the Python build system for the
+new PGEN_FOR_BUILD variable, so that we can point Python ./configure
+script to the pgen program that have been previously built for the
+host.
+
+Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
+later significantly reworked by Thomas Petazzoni
+<thomas.petazzoni@free-electrons.com>, with some inspiration taken
+from the Python patches of the PTXdist project, and then ported to
+python3.3 by Maxime Ripard <maxime.ripard@free-electrons.com>
