Bug#857538: proj-data: Package uninstallable when cross-building

[Dima Kogan]

Package: proj-data
Version: 4.9.3-1
Severity: normal

Hi. It is currently impossible to install anything that eventually
depends on proj-data (libproj12, libgdal20, libgdal-dev) when
cross-building because proj-data cannot satisfy foreign-arch
dependencies. This can easily be done with the attached patch.

The patch also declares libproj12 an libproj-dev as coinstallable across
multiple arches, another useful thing for cross-building.

Thanks.
