The build tree should be linking against the build tree
(non-installed) libs.

I understand your goal, but that's not how we're currently doing it.
If you've got a suggestion (and a patch) to handle this robustly both
ways, I'm willing to entertain it.

What I want to be sure that we can do is to run make check against the
non-installed libraries prior to installation.

Is NetBSD using a vanilla version of libtool, or a modified version?

At least under GNU/Linux the unmodified libtool does what I expect
(supports testing against non-installed libs), and relinks against the
install path as part of installation.  The Ubuntu folks have patched
libtool in a way that breaks the ability to test before installing.
Putting it mildly, I think they're out of their minds ;)
