The other tested serial interface code is that in arch/r8c/terminal.fs.  What
was changed in 0.7 is that key_avail no longer uses ioctl with FIONREAD to
check, but select, because ioctl(... FIONREAD ...) breaks under some
circumstances.  Maybe, however, select breaks on serial lines.  The code in
terminal.fs uses ioctl, by having its own C binding to it.
