From 0054a52bd818fc1ef33684b8b8a8decd60fe4cee Mon Sep 17 00:00:00 2001

Subject: [PATCH] tar seems to ignore the XZ_OPT variable sometimes

This caused that the xz command was called without any
extra arguments. This will now create the tar archive
first and then pass the archive through xz with our
command line switches.
