[aarch64-port-dev ] jdk/jdk ci builds

[Stuart Monteith]

Hello,
   I've added a new build that is triggered once an hour if there has
been a change to the jdk/jdk repository. It does nothing more than
build a fast debug build, so it exists just to catch code that
introduces build failures.

Emails will be sent on the first failure, and once the build has been fixed.

All of the builds, successful or otherwise, can be seen here:
   https://ci.linaro.org/job/jdkX-ci-build/

This is on the original build machine which got overloaded and
eventually broke. There should be proper daily builds coming from it's
replacement soon.


BR,
   Stuart
