Cross compile jdk8u on PPC32

[Volker Simonis]

Hi Radu,

ppc32 is currently not supported in the main OpenJDK repositories. You can
of course use the zero variant, but that's interpreter only, so the
performance won't be great.

As far as I know, Azul supports ppc32 but I'm not sure where they are
hosting their sources. CC'ed Ivan from Azul who may know.

Regards,
Volker
