Comment 2 for bug 1676058

@Gunnar : you are too fast for me. I would have checked out desktop docs eventually, particularity since that is where I stole that part of the Serverguide Makefile from in the first place.

Because builds with a 14.04 computer used to work fine and that part of the Makefile is so old, I can only assume that yelp-build didn't use to put in the doctype directive, but that now it does. However, I'm not going waste time figuring it out for certain.
