Subject: [PATCH] Turn on new termios for x86 32bit systems.

I've been running this way on my laptop for some time with no problems so
it's time to turn it on for everyone. Unless you've got a hacked libc you
shouldn't even notice this change.

<hint>
(Note to other platform maintainers: those who've not made changes for their
platform soon after all the hints will find me submitting patches for their
platform. So if you want particular encodings you might want to do it soon)
</hint>
