RFR (M): 8036767 PPC64: Support for little endian execution model

[Lindenmaier, Goetz]

Hi Sasha, 

I still get a small problem in ppc64.make.  You need to remove the space 
before big and little in the assignment:
  OPENJDK_TARGET_CPU_ENDIAN := $(if $(filter ppc64le,$(shell uname -m)),little,big)
My build ran into the 'little' case below, as I understand because ' big' was compared 
with 'big'.  Make is strange ...

After fixing that, tested linuxppc64, aix and linuxx86_64, they all work.

Best regards,
  Goetz.

I've fixed make/linux/makefile/defs.make to remap ARCH
from ppc64le to ppc64.
I have fixed make/linux/makefiles/ppc64.make to set
OPENJDK_TARGET_CPU_ENDIAN if it hasn't been set by the caller.

Sorry, I forgot to resync with another repository. Done.
