Bug#971720: tumbler FTCBFS: gtk-doc runs host code

[Helmut Grohne <helmut@subdivi.de>]

Source: tumbler
Version: 0.2.7-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs

tumbler fails to cross build from source, because it runs host code via
gtk-doc. Practically, gtk-doc doesn't work at all in cross builds.
Fortunately, the generated documentation is separated into an arch:all
package here, so we can just disable gtk-doc in arch-only builds (such
as cross builds) and make tumbler cross buildable. Please consider
applying the attached patch.
