Well lets start with, is this an issue at all? I never run MAKEALL
from oe as it taints my environment. Thanks to Masahiro, deployment
should not depend on python at all. Developers can install the required
python version themselves, even if they don't have root priviliges, since
env can pick it up.

Furthermore the tool chains are there to provide the needed tools, so to
insist on using the host version is exactly the opposite of what they want
to achieve.
