Hi,

Could I please get reviews for this JDK 8 backport which fixes some
tooling issues on Linux ppc64le? Prior this patch, a ppc64le build
would report as "ppc64" via os.arch system property which breaks
tooling such as maven in as much as if some dependency needs native
libraries it would download BE binaries where it actually should
download LE binaries. Example for os.arch/java.library.path:

pre:
$ ./jdk8-pre-ppc64le/bin/java TestProperty
java.library.path = /usr/java/packages/lib/ppc64:/usr/lib64:/lib64:/lib:/usr/lib
os.arch = ppc64

post:
$ ./jdk8-post-ppc64le/bin/java TestProperty
java.library.path = /usr/java/packages/lib/ppc64le:/usr/lib64:/lib64:/lib:/usr/lib
os.arch = ppc64le

Bug: https://bugs.openjdk.java.net/browse/JDK-8073139
webrevs: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8073139/jdk8/01/

Including build-dev for build changes. hotspot-dev and ppc-aix-port-dev 
for JDK/hotspot changes.

This backport should only have minor differences to the changes in JDK
11. We have been using similar patches in Fedora for months. Thoughts?

Thanks,
Severin
