POWER10 seems to work nicely with sbefifo (modulo the start
SBE command being buggy with stop states -- make sure you
stop and start using -b kernel backend when testing this).

gdbserver itself was due for a bit of attention. It still really
needs proper all-stop multi threaded support that can take over
all threads and start/stop them. Because all threads on a chiplet
have to be stopped to debug it, but if we only control one
thread with the debugger then continuing execution is rarely
useful outside controlled special cases.

Thanks,
Nick
