I guess you just have to build once with the host cross-gdb
selected and then a second time with target gdb-server
selected.  That doesn't really make sense to me. I don't see
why they can't be built at the same time -- they should be
separate packages, not different "versions" of a single
package.

Now that I've gotten both of them built, I can't seem to get
them to work when debugging a multi-threaded applications.  I
can "next" through main() as it starts up the threads, but
after that, gdb has no clue what's going on. Gdb only shows 1
thread, and when I stop the program, gdb seems clueless about
what is running.  All it displays is "0xNNNNNNNN in ()?".

When I debug the exact same program on IA32, gdb knows about
all of the threads, and it can switch to and display
information about each of the threads.

Is thread debugging not supported on PPC?
