ldd and ldconfig do look in these directories (I mean /lib32 and 
/usr/lib32, but they follow the symlinks), even without the symlink in 
/lib/ldconfig, so if dpkg-shlibdeps does not look in this directory, I 
think the bug is in this tool.

Again, ldconfig was only intend for multiarch, please don't use this 
directory for other things. Moreover it is not needed here.

As explained above, this only a workaround, not a fix. The fix has to be 
done in dpkg-shlibdeps, that's why I am reassigning this package to dpkg.
