Can someone please summarize the problems we need to address?

Again, it is my believe that changing configure.in to define unlibsubdir
to "." in those cases where it can not be made to work should fix both
problems.

But I may not understand the problems fully, so please explain
both problems we're having in detail.

No, that's not the right approach.  If that's required, then the problem lies
elsewhere.
