--as-needed needs to come before the object files and libs to be effective but libtool moves it to the end. This happens with both 1.5.26 and cvs head.

The fact that libtool reorders _any_ of the command-line is a bug. I
think Ralf has a fix for this but I don't think it'll happen until 2.1
or 2.2.


Still there in libtool 2.2
