Yes; you have to configure and build gdb as if you wanted it to
run native on the ppc; only then can you configure and build gdbserver.

Heh.  gdbserver is broken at the moment.  I posted recently with
almost identical questions.  There is talk of fixing it, but I
don't know if anyone's working on it.  Similarly, there's talk
of making it handle multithreaded programs, but I don't know
if anyone's working on that, either.
