Thanks Arnd !!

This fix solves the config issue, but adds an unnecessary MODULES 
dependency on APPRAISE_MODSIG. APPRAISE_MODSIG can be used for kernel 
image(appended signature) as well as for kernel modules.

I am working on the fix. I am sorry for the delay, I got stuck with some 
urgent issues early this week.

Thanks & Regards,
