[PATCH 01/19] tests/hwtable: set multipath_dir in local configuration

[Martin Wilck <mwilck@suse.com>]

If internal libmultipath APIs change (such as, recently, the
checker API), test programs will fail because they'll link
with the standard system prioritizer / checker / foreign APIs.

Make sure we always link with our own shared libraries.
