Commit ef5f5c8659b1ca3999e362dfa33478e0a0150ced implements a ‘configure’
check such that one gets an error for obvious misconfiguration, and a
warning when the user passed an explicit --localstatedir flag that does
not match (“I know what I’m doing”.)

I believe that should avoid the most common issue.

Comments welcome!
