[8u] RFR: 8073139: PPC64: User-visible arch directory and os.arch value on ppc64le cause issues with Java tooling

[David Holmes]

Hi Severin,

Changes present seem okay, but I don't see the SA changes, and don't you 
want the JDK test change from this as well:

http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/2ff471390a03

??

Thanks,
David
