Thanks to your patch I decided to leave i386 for the moment but its
definitely a candidate for removal.

So I did but was running into new problems which are caused by the hand
craftet build system (yes, I tried to convince upstream to use some of
the usual candidates but failed :-((( ).  I was able to add some missing
libs in pbuilder chroot but whatever trick I try[1] the build system
always constructs a different command line than I tested inside the
pbuilder chroot.

Do you have any idea to stop this insane messing up with library options?
