It is somewhat intentional that components do not depend on each other
like this. Someone that has only specific requirements may not need
those detections, so we generally do not force anything like that.
Anyone who wants a very minimal build needs to configure components
very carefully, specifically because of these interactions.

Note that _suggest serves a different purpose in configure then one
might know from other systems, and would not be appropriate.
