Unfortunately, I can't reproduce this at all. What I find strange is
that the dynamic linker expands $LIB to "lib64" on your machine,
whereas (if I'm not mistaken) on Debian, it should expand to the
correct multiarch triplet for you (x86_64-linux-gnu).

And that shouldn't "fix" this issue anyhow. BUILD_LIBDIR is only used
to specify where we place the library in the _build_ tree, so we (or
rather, dh_install) know where to look for it when we generate the
debs.
