There is interest, and I have seen some attempt at work on it however
it is not something likely to bear much fruit because mdb knows nothing
about dwarf; AFAICT it knows only about stabs, which we don't use
at all.

Also, Oracle did make some Dtrace enhancements in upstream gdb that
would be good to port.
