Bug#940618: mark libmapbox-variant-dev Multi-Arch: foreign

[Helmut Grohne]

Package: libmapbox-variant-dev
Version: 1.1.6-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability
Control: affects -1 + src:node-mapnik src:python-mapnik src:mapnik src:viking

The affected packages fail to satisfy their cross Build-Depends, because
their (transitive) dependency on libmapbox-variant-dev is unsatisfiably.
In general, Architecture: all packages can never satisfy cross build
dependencies unless marked Multi-Arch: foreign or annotated :native. In
this case, the foreign marking is appropriate, because
libmapbox-variant-dev is a header-only library that entirely lacks
dependencies and maintainer scripts. Please consider applying the
attached patch.
