[RFE] Support building Graal VM with native-image with OpenJDK 11 #2196
Description
Describe GraalVM and your environment :
- GraalVM version: master, 998163d
- CE
- Build Time or run time failure: build time
- JDK version: 11.0.6+10
$ java -version
openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment 18.9 (build 11.0.6+10)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.6+10, mixed mode)
I've got latest OpenJDK 11.0.6+10 release retrieved from the upstream project[1]. It would be nice if there was a supported way to use a built-from-source JDK to build graal ce with native-image. Currently I'm getting this:

Here is my build script:

$ MX="/path/to/mx --java-home=$OPENJDK"
$ rm -rf substratevm/svmbuild
$ pushd substratevm
$ cat > HelloWorld.java <<EOF
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
EOF

One needs to get a JDK 11 from [2], but that's a black box and Graal CE should support a clean build-from-source bootstrap approach.
