Tar will hard-error with the message:
tar: ./include/**.h: Not found in archive
tar: Exiting with failure status due to previous errors
if the temppack.tar does not contain a match. We have to use a special
module to silence this match for several reasons.
- There is no way to ignore this error (even though it has been
requested on the GNU tar mailing list).
- We cannot redirect the output of tar to /dev/null easily. We have to
use the LIST form of system which does not allow for redirection.
