Finally took the ten minutes to do this backport of JDK-7181710 for JDK 8.

Please review my changeset for JDK-8016096:
http://cr.openjdk.java.net/~ddehaven/8016096/jdk.0/

Issue:
http://bugs.sun.com/view_bug.do?bug_id=8016096

7u issue (more info):
http://bugs.sun.com/view_bug.do?bug_id=7181710

Basically an almost direct backport of the 7u changeset, modified for the new build system (much simpler). I also removed X11 toolkit support as Artem (I think?) mentioned we will not be shipping with an X11 toolkit for JDK 8. I did not touch the old build system as it's slated for removal anyways.

Mac build was fine, submitting a JPRT run to ensure other platforms are not affected.

I'll need a sponsor for this one too.
