mytest is the same executable you run on the target. gdb you run on
the host would be powerpc-linux-gdb (i.e., cross-debugger), thus:

target:> gdbserver :6666 ./mytest

host:> powerpc-linux-gdb mytest
[...]
(gdb) target remote mytarget:6666

mytest is compiled with powerpc-linux-gcc.

Yes I know their email addresses. But you don't want to hassle them
with this. Trust me :)
