    Description

      The current method to build against DKMS installs of ZFS and SPL
      assumes directories like this:

         /var/lib/dkms/spl/${VERSION}/build
   /var/lib/dkms/zfs/${VERSION}/build

      Unfortunately, that "build" directory was really just a temporary
      step in the DKMS build process. Older versions of DKMS forgot to
      clean up that directory, but in RHEL7 at least, DKMS no longer
      leaves that around.

      Instead we need to look in these places for source code:

        /var/lib/dkms/spl/${VERSION}/source
  /var/lib/dkms/zfs/${VERSION}/source

      and in these places for the per-kernel object info:

        /var/lib/dkms/spl/${VERSION}/${LINUXRELEASE}/${target_cpu}
  /var/lib/dkms/zfs/${VERSION}/${LINUXRELEASE}/${target_cpu}

      The changes in this patch update the Lustre build system to
      look in those corrected directories for DKMS builds of SPL
      and ZFS.
