RFR: JDK8u back port of JDK-8047763, JDK-8042059, JDK-8046408, JDK-8048232, JDK-8046471, JDK-8046611 and JDK-8044363

[Mikael Vidstedt]

Changes look good.

This is touching PPC specific logic in the makefiles - the same logic I 
accidentally broke in the original change for[1], which resulted in[2]. 
I've cc:ed the PPC folks, hopefully they can help verify that this works 
as expected.

Cheers,
Mikael
