We're starting to get overloaded with the CONFIG_HAVE_* options.

We need to start consolidating them. I would like to make RETVAL and FREGS
into one option. We can add this now, but before we add anything else, we
need to see what HAVE configs have the same archs, and then just
consolidate them. If an new arch wants to add one of the consolidated
features, it will also need to add all the other features that were
consolidated with it.
