The initial integration of macosx changes to jdk8 depended on a hotspot change that was not included in the changeset.

Initially it was thought that hotspot should include this change and it was put into hs mainline
through 7152031.

But, it now looks like we should back out that change and make JDK use the intended naming scheme
for AWT libs as on other platforms. ie no longer use sub-directories for the toolkit type eg (xawt).
This will be compatible with current hotspot behavior.
