Sorry, no better suggestion right now.  Clearly it is not working as
anyone expects.  We gotta decide what we want it to do, make it actually
do that, and document it.  Or maybe document it, then make it work the
way we documented.

For now, the key concept is that --prefix only has effect (works) at
install time.  People keep suggesting the resulting installed stuff is
different for a different --prefix.  That is not the case and needs to
be explicitly mentioned in the doc.

Yup, just confirmed that.
