The IA64 port of Linux has no maintainer, and according to a report from
its only remaining user [0], it has been broken for a month and nobody
cares.

Given that keeping a complex but unused architecture alive uses up
valuable developer bandwidth, let's just get rid of it.

This supersedes my patch proposing to mark it as 'dead', which received
no replies from anyone that wants to keep it alive. [1]
