It helps to test gdb running qemu instead of a gdbserver.
It prints the same message as the gdbserver on startup.

Not really - we don't arbitrarily output stuff on stdout. In fact the
best way to track what gdbserver is doing is to use the built-in trace
points:
$QEMU -d trace:gdb\* $QEMU_ARGS
For system emulation from the console you can run:
(qemu) info chardev
which will report the state of the gdb connection:
gdb: filename=disconnected:tcp:0.0.0.0:1234,server

> if (!gdb_accept()) {
> close(gdbserver_fd);
