I was aware of duck, but as stated by Jakub, that is a non-option for
lintian. In addition many of these URLs are (or were at the time)
still reachable, but might disappear in the near future, and we know
beforehand that they are obsolete, so I think they are really good
candidates for a lintian check, because the just require a string
match instead of a network check.

Thanks,
