Temurin-build: Provide a new platform linux-x64 with ZGC enabled
Hi !
Today, I wanted to play a bit with ZGC. I downloaded the release jdk8u172-b11 on https://adoptopenjdk.net/, and I was surprised to see this log when starting my application:
Unrecognized VM option 'UseZGC'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
From what I can see here, ZGC needs to be enabled with at compile time with a sh configure --with-jvm-features=zgc
I know that zGC is considered experimental, but I think it will help developers to be able to retrieve a linux-x64 platform with zGC enabled. As ZGC is currently only available on Linux/x64, we could only add a special platform target, something like OpenJDK11-jdk_x64_linux_hotspot_zgc for example?

@PierreZ It looks like that requires a HEAD build (i.e. it's not in the JDK8 codebase)

looks like jdk 11.0.3+ builds will enable it by default according to this page

If you are building early versions of JDK 11 (versions 11.0.0, 11.0.1 or 11.0.2), you need to supply the configure option
--with-jvm-features=zgcto enable building of ZGC. This option is no longer needed (ZGC is built by default) as of JDK 11.0.3 and JDK 12.
