I've added tuning for gcd and gcdext now. There's actually only two
new tuning values:

GCD_THRESHOLD
GCDEXT_THRESHOLD

For machines where these are not defined, relatively good default
values are provided. But we should run make tune and put these two
values in for each of the arches we support.

I've added tuning values for core2/penryn and k102 already.

Bill.
