If you look at patch 4/5 in my original series, that just what you're
proposing here: a gdbserver that speaks only SPU.  We've been using
that to support x86 -> spu cross debugging, but it would certainly
work for ppc -> spu cross debugging as well.

However, the patch has the same type of slight abuse of the build system
that Mark was concerned about for the native patch: it has a hack to build
a gdbserver in a "cross" configure situation.  Since I can't really build
a native spu configuration, that's the only way to actually get a gdbserver
built I could think of ...
