Hum, right, ok. I'm not a big fan of how we handle intltool, but I
admit that the main reason for this mess is me asking you to not make
intltool and libxml-parser-perl depend on host-perl.

I've applied your patch (after slightly rewording the commit log), it
indeed seems to fix the issue. We'll see how things go, but I'm not
very happy with our intltool handling :/

Best regards,

Thomas
