toplevel configure.in: small rearrangement

[Nathanael Nerode]

I'm back.

This moves one of the definitions of CC a bit lower; when I autoconfiscate, 
it's much easier if all the logic related to CC is as close as possible, and
also if all the fragment collection code is uninterrupted by other things.

Tested, no behavior changes.
