[Mesa-dev] [PATCH 2/2] configure.ac: error out if python/mako is not found when required

[Emil Velikov]

In case of using a distribution tarball (or a dirty git tree) one can
have the generated sources locally. Make configure.ac error out
otherwise, to alert that about the unmet requirement(s) of python/mako.
