There used to be a multiplexer, called kdmx, that allowed you to use
one port for both console and debug. But I haven't seen a copy of it
in a few years now.
The inappropriate ioctl message can probably be ignored. If you tell
gdbserver to write its stdout/stderr to /dev/null and to open a
connection to /dev/ttyS0, it should work.
