Building Graal with JVMCI JDK8 on Aarch64

[Foivos Zakkak]

Hello all,

We are trying to build Graal on top of JVMCI JDK8 on Aarch64, but we
fail to get JVMCI JDK8 to build.

We use:
1. the latest mx (11c0b3dab35110bcef853e30ca9ee18615451fe0) from github.
2. Oracle's jdk8u151 for aarch64 jdk-8u151-linux-arm64-vfp-hflt.tar.gz
3. gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.6) 5.4.0 20160609

When running:
hg clone http://hg.openjdk.java.net/graal/graal-jvmci-8
cd graal-jvmci-8
mx --java-home /path/to/jdk8 build

We get:

WARNING: No platform-specific definition is available for distribution JVM_PRODUCT_SERVER for your architecture (aarch64)

and later the error:

Generating precompiled header precompiled.hpp.gch
g++: error: unrecognized command line option '-m64'

Does JVMCI JDK8 support Aarch64? Are we doing something wrong?

Kind regards
