[Toybox] [PATCH] python2 probing

[Elie De Brauwer]

Hello Rob, list,

I just found the README.txt in the generated folder, obviously my
patch won't play nice if you plan to ship generated help.h's. Hence
complaining due to absence of python isn't that polite either, so the
check would probably be something like 'if python not found, and
help.h isn't there, and help is requested' then complain. Which will
then only happen when working from mercurial and not from source
tarballs, ... but this is imho a rather awkward situation ...

E.
