The related question is: How do we ship CFFI modules in PyPy? Import all
the cffi modules once after translation to produce the cached shared
libraries?

That sounds reasonable. I guess it should print something about that and
exit 0.

Is there going to be a backend API version that's independent of the
cffi version?

At any rate, reporting that the backend is incompatible with the
requested cffi seems reasonable.
