-lz gets translated into /usr/lib/libz.so

[Jaap de Jong <jaap.dejong@nedap.com>]

Building openjdk-6 still ends in an error (or again?)
Looking at the log file reveals that the -lz option is somehow replaced 
by /usr/lib/libz.so
Is there anyone with a hint in the right direction?
Is this a libtool issue?
