A couple of notes:

1. Did you find something that required zlib-devel to be installed? With Use bundled zlib on all versions, not just 21 temurin-build#3459 the JDK should no longer require it for build purposes
2. I didn't realise we still had 32-bit stuff being installed in here. Don't think it's something that adoptium uses (we've never built for 32-bit xlinux) but we should perhaps check with IBM (@AdamBrousseau @sej-jackson ?) to see if they still have a requirement for those and if not, consider stripping it out to reduce complexity here.

Happy to approve in the meantime especially to alleviate the initial concern.

I've tried both build and test without zlib ( building fails due to missing X11, ALSA & Fontconfig dependencies, ), of which the Fontconfig does have a dependency on zlib ( which isn't installed by default on SLES 12 at least ).. Im inclined to leave it for the moment, and do some further investigation.
