But why build aarch64-zero and ppc64el-zero to begin with? Those platforms are fully supported by Red Hat's AArch64 port and SAP's PPC64 port, and are cleanly buildable: https://builds.shipilev.net/openjdk-jdk/

This must be why it went unnoticed: Zero is usually built for platforms without full-fledged ports. usually the hotspot platforms are faster to build, and before starting to debug zero-only platforms it might be easier to build and look at hotspot platforms where zero still builds. As I said, I didn't build zero-only platforms yet.

Sorry, I am confused, what is "hotspot platforms"? You mean jvm-variant=server? My point is, I don't think there are lots of people who care (read: maintain) about Zero variant for platforms that are supported by their corresponding ports.

Anyhow, aarch64-zero and ppc64le-zero seem to build with this fix: https://bugs.openjdk.java.net/browse/JDK-8214787

P.S. I think it also falls victim to resurfaced cross-compilation issue: https://bugs.openjdk.java.net/browse/JDK-8203828

...but that is workaroundable with specifying the --with-build-jdk.
