Bug#1087294: json-glib FTCBFS: unsatisfiable documentation build dependencies

[Helmut Grohne]

Source: json-glib
Version: 1.10.0+ds-2
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

json-glib cannot be cross built from source, because a number of
Build-Depends cannot be satisfied. A quick look indicates that most of
them are related to building documentation. Whilst there is a separate
-doc package that is Arch:all, the documentation is still built in
arch-only builds. Passing -Ddocumentation=disabled avoids that. Once
doing so, a fair number of dependencies can be moved to B-D-I and then
the remaining B-D become cross-satisfiable. I'm attaching a patch with
the necessary changes for your convenience. Unfortunately, json-glib
does not yet become cross buildable for reasons outside the control of
json-glib.
