Bug#593966: libc6: system-breaking (init OOPS) incompatibility with old prelink versions

[Andreas Mohr <andi@lisas.de>]

Actually I'm not sure any more whether this is "a __severe__ problem for
a branch-hopping minority(?) only":

Boyd Stephen Smith Jr. realized that this might very well become a problem
for "normal" branch upgrades from Lenny to Squeeze.
If Squeeze libc6 upgrade processing happens before the upgrade of the prelink
binary (and I think it does, since I believe libc6 upgrades happen
rather early during an upgrade operation, before many other packages),
we're ending up with the critical constellation during a normal upgrade as well.
And since on a P3/500/512, a full Ubuntu upgrade I did once took >> 8 hours
(possibly even longer with more modern installations),
due to the slow performance there's a rather high chance to hit the
cron.daily 24 hour processing's race window.
