It's at the expense of platform directory being ppc64/ instead of the
conventional ppc64le/,
and having rather ugly check in the ppc64.make file.

configure script writes hotspot-spec.gmk file to the top-level build directory,
and it contains
ZERO_ENDIANNESS=$(OPENJDK_TARGET_CPU_ENDIAN)

The patch contains the fuse in ppc64.make, the build will fail unless
ZERO_ENDIANNESS is set.

Sorry, this is not needed, it's the problem with the toolchain I am using.

Please ignore this patch.
