This seems to be cause by pkg-config, who think it's a good idea to
link to all libraries.

Adding a Depends from libssl-dev to libz-dev should fix
this, since this is atleast required for static linking, and as
long as we support static linking this is needed.

But the proper fix is to generate .pc files that don't tell you
to link to -lz for shared linking.
