Some of the python2 patches were left behind when doing the python3 package. This was because the python build system can now autodetect what packages can be built in the system. However, some of these patches are actually useful to reduce drastically the size of the interpreter. This patch ports the relevant patches to the python3 package, and adds a new patch to remove the idle3 IDE as well from the interpreter.

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>
