If you want to change the way python is ran I'd start by looking at this code. If this script could automatically try 'python2' if 'python' is found to be Python 3, and ensure the correct interpreter is used in all commands that run after the environment is setup that would be fantastic. It'd probably be a mess to implement though. The change as it currently stands looks confusing as py_v3_check is set by running python2. I used to use a virtualenv to temporarily set Python 2 as the default for the shell in which I ran bitbake commands. That was a while ago though, all my current builds are running on Ubuntu 12.04/14.04 server instances which I access via ssh from my Arch Linux box.
