Package: gcc-multilib-i686-linux-gnu,gcc-multilib-x86-64-linux-gnu
Version: 4:15.2.0-5+b1
Tags: patch
User: [email protected]
Usertags: cross-satisfiability
Control: affects -1 + src:zlib

A dependency on gcc-multilib does not work for cross compilation. This
can be worked around via gcc-multilib-TRIPLET. Unfortunately, those
packages are not presently Multi-Arch: same. They really should be as
their target architecture is encoded into the package name. I'm
attaching a patch for your convenience.

Helmut
