It's not just the build system that is affected. We also have a testsuite that
will have to cope with some builds that don't support certain NDR features -
and we should probably get some buildfarm machines to build without zlib. Users
will get confused becaused their carefully built Samba somehow doesn't support
AD, or their OpenChange doesn't work.

If we want to support systems without zlib installed, then the
current status quo (with Samba optionally using a bundled zlib) is so bad.
