We have a debugging library which is part of sane-backends. It allows you
to set an environment variable, and which causes the backend to print
messages to STDERR. If your backend is part of sane-backends, you can use
this library. If you backend is outside of sane-backends, you can certainly
setup something similar in your backend. You should not have to recompile
the frontend.
