And for two, autoconf is really meant to probe differences between 
platforms.  We'd just be probing the features provided by rumprun, and I 
sure hope we know what that env provides even without running probes.

Sure.  In-tree NetBSD has different requirements from not-in-tree 
NetBSD, so there's no real requirement to keep the two the same.  The
