Thank you for your report. I just fail to understand it, still. I just checked the source code and the arch already comes from dpkg-architecture. The latest with #711843 this should all be an issue of the past. I to do not see why it works on amd64 but not for e.g. i386.
I need a mental reset, will look at it later again. Steffen -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
