Could you explain why you take i686 package from x86-32 repository and check
it against x86_64 repository?
As far as I know alternative-architecture multi-lib packages are distributed
in the same repository as packages for the main architectue. E.g.
glibc-devel.i686 is in x86_64 repository, hence glibc-devel is mutlilib.
glibc-headers.i686 is not in the the x86_64, hence glibc-headers is not
multi-lib.

Are you building miniz as multilib? Depcheck checks the x86_64 and i686
repos separately; it is not pulling out of the i686 repo here.
