[Pkg-nagios-devel] Bug#852916: icinga-web: FTBFS: checking if php has xsl module... configure: error: not found

As can be seen from the build log, the resolver installs both php7.0 and
php7.1 dependencies (namely php7.1-common and php7.1-xml), resulting in
a php cli environment based on 7.0 that does not have the xml/xsl
modules available. This also happens in my sbuild chroot. It cannot
happen in Stretch, though, because php7.1-xml is only available in
unstable. So this bug does not affect Stretch.

I suspect the cause for this peculiar behaviour of the apt resolver has
to do with the Build-Depends on php-xsl, which is a purely virtual
package currently provided by both php7.0-xml and php7.1-xml. It goes
away when I change the Build-Dependency to php-xml.
