Building OS X with SYSTEM_ZLIB=true

[Michael Franz]

Hi,

I am trying to build the bsd-port using the system zlib.  I get two build
errors when I do this:
Undefined symbols:
  "_inflateEnd", referenced from:
      _inflate_file in libjli.a(parse_manifest.o)
  "_inflateInit2_", referenced from:
      _inflate_file in libjli.a(parse_manifest.o)

These were fixed by applying this patch.  Without looking too deep into
this, I feel that the patches should not be necessary as OS X has libz/zlib
and the build works for FreeBSD and OpenBSD.
