Rebuild zLib. Use -fPIC when building it.

zlib is an old makefile-based library. You usually need to patch it
heavily to get it to honor CPPFLAGS, CFLAGS and CXXFLAGS. The easiest
thing to do would be open the makefile and just add the flag by hand.

Here's an example of a zlib patch to generalize the makefile so it
honors user flags:
