[aarch64-port-dev ] RFR: 8081294: aarch64: fails to build on ubuntu wily

[Edward Nevill]

Hi,

One of our partners has reported that jdk9 fails to build for aarch64 on ubuntu 'wily'

The failing buildlog is here

https://launchpad.net/ubuntu/+source/openjdk-9/9~b64-1ubuntu1/+build/7441971

The following webrev fixes this

http://cr.openjdk.java.net/~enevill/8081294/webrev/

I have verified that this fixes the problem by cross compiling against a sysroot.

Our partner has also verified that this patch fixes the build.

As this is a change to shared code I will need someone to sponsor this and push it through JPRT.

Thanks for your help,
Ed
