Happy to report that after today's push of conditional GC compilation, zgc/zgc builds successfully
in these configurations: {Linux} x {x86_64, x86_32, aarch64, arm32, ppc64el, s390x} x {server,
minimal, zero}.

x86_32 build successfully reports:

$ jdk/bin/java -XX:+UseZGC -version
OpenJDK Server VM warning: -XX:+UseZGC not supported in this VM
