Debian 8 is running on a real system, no VM etc.
I used netinstall with no desktop environment and without all the blows 
and whistles and added just what I needed, when I needed it.
This machine was used for the last 1,5 years or so for developing on 
Krogoth.
I was able to reproduce the problem on a second box, real machine, 
running Debian 8

Meanwhile I tried building rocko on another real machine, running Debian 
9 - it works. ( in the prev email I tested in a Debian 9 VM)

Thanks
