Why is a patch needed?

Doing the following seems to be sufficient:

diff --git a/package/openzwave/openzwave.mk b/package/openzwave/openzwave.mk
index 2723086..9c50cb8 100644
--- a/package/openzwave/openzwave.mk
+++ b/package/openzwave/openzwave.mk
@@ -29,7 +29,8 @@ OPENZWAVE_MAKE_OPTS = \
        instlibdir=/usr/lib \
        pkgconfigdir=/usr/lib/pkgconfig \
        sysconfdir=/etc/openzwave \
-       DOXYGEN=
+       DOXYGEN= \
+       LIBDIR=$(@D)
 
 define OPENZWAVE_BUILD_CMDS
        $(TARGET_MAKE_ENV) $(MAKE) $(OPENZWAVE_MAKE_OPTS) -C $(@D)

If you agree with this, could you submit a patch with this solution,
preferably after adding a comment that explains why we're passing such
a strange value for LIBDIR.

Of course, please submit a bug report to the upstream project.

Thanks a lot!
