Bug#1021966: dkms: line 1055: kmodsign: command not found

[Paul Wise]

Package: dkms
Version: 3.0.6-3
Severity: minor
Usertags: warnings

I noticed that during upgrades dkms now complains about kmodsign not
being available and that kmodsign is not yet available in Debian. 

Despite the message, on a BIOS system I can still install/load modules
and it appears sign-file from linux-kbuild is used instead later on, so
probably module install/load still works on UEFI systems too.
