Thanks.  This is still not complete, though.

You need to make sure that the "multi_process" flag stays turned off
if the backend doesn't support MP, otherwise, things like
remote-utils.c:write_ptid will still misbehave (gdb will realize the
target doesn't support multi-process, but the remote target will
be replying with multi-process packets, how odd would that be?!).
That flag is currently bound to GDB's multi-process support,
because current gdbserver is assuming all backends support mp.

	    /* Record if GDB knows about multiprocess support.  */
	    if (strcmp (p, "multiprocess+") == 0)
	      multi_process = 1;


To see this in action, you can connect with
"target extended-remote :foo"/"set debug remote 1", and make sure that
the packets flowing in both directions don't use multi-process thread
id extensions (e.g., 'p1.1' vs '1').
