+Add support in Python build system to specify host tools
+
+Python needs a Python interpreter and a "pgen" program to build
+itself. Unfortunately, the Python build system assumes that it can use
+the interpreter and pgen program it has just built to build
+itself. Obviously, this cannot work in cross-compilation mode since
+the interpreter and the pgen program have been built for the target.
+
+Therefore, this patch adds support in the Python build system for the
+new PYTHON_FOR_BUILD and PGEN_FOR_BUILD variables, so that we can
+point Python ./configure script to the Python interpreter and 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.
+
+Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
