So we're going to need another gcc merge?

On the subject of `Embarrassing', I've been making an assertion for a
while which I've just discovered is out of date.  gcc supports scheduling
for processors after pa7200.  It now supports -mschedule= 700, 7100,
7100LC, 7200, 8000 and -march= 1.0, 1.1 and 2.0.

So I think I'm going to add config options to the kernel to allow people
to optimise for this, just like x86 does.
