When using the top-level build from configure, there is a 
OPENJDK_TARGET_CPU_ENDIAN variable defined already, set to "big" or 

I assume that you will need to add support to ppc64le into the top-level 
and jdk make files as well. Building just hotspot for ppc64le, but not 
any of the jdk native libraries, does not really make sense.
