Libtool has been slain

So the big package move from Testing into Current/Extra is complete. Big thanks to Tpowa, JGC, Blaasvis and neri for orchestrating it.

Incidentally, tomorrow is bug-squashing day, so it'd be a big help if people would pop into #arch-bugs on irc.freenode.net and help us identify/squash the bugs that will likely pop up after a big move like this.
