Cross compile jdk8u on PPC32

[Bob Vandette]

As others have mentioned, you need to target ZERO and not PPC32 when trying to build
a non supported cpu architecture with the Zero interpreter.

You do need to have a libffi.so binary available for the build.  Zero uses this to manage the
native stack frames.
