Also, I think I mentioned this in the v2 cover but not here, that having done

My question from v2 was: should we in fact convert back from gdb's errno to
host errno in
gdbstub.c handle_file_io(), and then let each semihosting backend convert from
host to guest?
That sounds like it's probably a better idea (though I'm not sure
what host errno we use for the gdb "unknown errno" case)...
