Bug#883563: libkfmime-dev is wrongly marked Multi-Arch: foreign

[Helmut Grohne <helmut@subdivi.de>]

Package: libkf5mime-dev
Version: 16.04.2-1
Severity: important
User: helmutg@debian.org
Usertags: rebootstrap

kmbox fails to cross build from source, because it cannot find
KF5MimeConfig.cmake. This file is supposedly located in libkf5mime-dev,
but it is located on an architecture-dependent path and pulled for the
wrong architecture. This is due to libkf5mime-dev being marked
Multi-Arch: foreign. Such a marking is wrong. Whenever it is installed
for a "wrong" architecture, libkf5mime-dev will simply be unusable even
for native builds. Please remove the erroneous marking.
