Could someone please confirm if the following command line invocation

I would expect this to be OK, but I have no idea what openvdb is or what it does, so there might be subtleties.
Using LD_PRELOAD= is something that generally works: some packages that
I maintain do this to run their build-time test suites, which can fail if
the fakeroot module was LD_PRELOADed[1].
Setting LD_LIBRARY_PATH is also something that generally works: basically
all Autotools packages with test suites do this to run their test suites.
It might be more conventional to use $(CURDIR)/debian/tmp/usr/lib/$(DEB_HOST_MULTIARCH) so that it's an
absolute path.
It would probably be useful to try running:
LD_PRELOAD= LD_LIBRARY_PATH=./debian/tmp/usr/lib/$(DEB_HOST_MULTIARCH) ./debian/tmp/usr/bin/vdb_print --version
just before this help2man invocation, so that if there is a linker error
or something, you will see it?
I also notice that the build-time tests are failing in experimental,
but their failure is ignored (except on sh4, which builds with DEB_BUILD_OPTIONS="nobench nocheck parallel=1" so it never even tries
to run the tests). The log says:
2: log4cplus:ERROR No appenders could be found for logger (openvdb).
2: log4cplus:ERROR Please initialize the log4cplus system properly.
Could this be failing early enough that it also breaks the ability to
run `vdb_print --help` and `vdb_print --version`?

[1] D-Bus-related packages want to know their real uid, and bubblewrap
doesn't work with fakeroot because fakeroot assumes a fully-functional
filesystem at all times, but bubblewrap needs to pass through a
state where the filesystem is non-functional while it sets up its
container.
