From what I have understood from your explanation, if the directory exists chroot_canon() will work, so `ldconfig -r` will be able to create the aux-cache file in it. I still think that the bug should be fixed on the glibc upstream side, but that would allow to easy fix it on the package side, and it's probably better to have a closer match of the dpkg database and the file system.
