There are no frontend-only or backend-only options.  Nearly all that
code is built into the shared libraries that are linked against and
loaded by both binaries.  That said, all physical tuner access is
performed by the backend, so it will make no difference what tuners are
enabled during compilation of MythTV on a dedicated frontend.
