[xml/sgml-pkgs] Bug#1120104: libxml2 FTBFS with the nopython build profile

[Helmut Grohne]

Source: libxml2
Version: 2.15.1+dfsg-0.3
Severity: important
Justification: breaks architecture cross bootstrap
Tags: patch ftbfs
User: helmutg at debian.org
Usertags: rebootstrap

libxml2 fails to build from source when enabling the nopython build 
profile. It implicitly enables the documentation build even when Python 
bindings are disabled, but doxygen is annotated <!nocheck>. This trips 
up configure. The easy way to fix this is to unconditionally install 
doxygen. Possibly, disabling the documentation build in more places 
would be a better solution. I'm attaching a patch for the simple one.
