Bug#819384: direwolf: FTBFS when built twice in a row

[Santiago Vila <sanvila@unex.es>]

Package: direwolf
Version: 1.2-2
Severity: important
Tags: patch

Hi. While we are at it, this package does not build twice in a row.
Please try:

dpkg-buildpackage
dpkg-buildpackage

and you will see how it fails. This happens because the clean target
does not remove "gen_fff".

Patch attached.

Thanks.
