[Pkg-utopia-maintainers] Bug#873596: avahi FTCBFS: uninstallable python Build-Depends, fails to figure out what distribution Debian is

[Helmut Grohne]

Source: avahi
Version: 0.6.32-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

avahi fails to cross build from source. Since xmltoman became
M-A:foreign. avahi's Build-Depends are almost installable. Its python
dependencies still fail with postinst errors. For cross building, one
typically wants libpython from the host architecture and the rest from
the build architecture. After annotating all of those dependencies,
./configure fails figuring out the target distribution. After telling it
that we build for Debian, it cross builds successfully. Please consider
applying the attached patch.
