none of the packages using scons works with python3 so we switch back to
python2 for now.

+Subject: [PATCH] Support python 2 print statements in SConscripts
+
+This fixes a regression introduced in scons-3.0.0, where
+SConscripts containing python 2 print statements would cause
+syntax errors even when executing scons with python 2.7.
+
+This ensures backward compatibility, allowing users to build
+legacy code with scons-3.0.0 without having to patch it.
