Revision 7780

Correct src/models/makefile to link --as-needed.

This patch was extracted from the monolithic patch at
http://launchpadlibrarian.net/79698350/wise_2.4.1-8_2.4.1-8ubuntu1.diff.gz
where the changes for this issue were convoluted with changes
related to glib.

I am a bit demotivated by receiving big debdiffs instead of proper patches.
It is not because I am not payed that my time is less precious.
