For flex and bison, we check if a generated source file exists, which
is probably a good idea. That way configure will fail in a git
checkout if you don't have python.

I have in my todo list to add some remaining source files generated by
python to the autotools distribution. After we commit some version of
this patch, Emil or I should make sure that all the python-generated
code is included in the tarball.
