I was running native applications (compiling and debugging DOS
applications under DOS).  No cross-compiling was involved.

Perhaps GDB needs to be built for the PowerPC with knowledge of each
opcode, and the privileged opcodes were not part of the machine
description file it uses, because it would not be possible to debug a
native PowerPC application in that fashion, and the designers failed
to anticipate the possibility of cross-platform emulation.  That is
pure speculation on my part, and not too likely, I guess.
