ehh, why use the term ppc on a ppc64 system? ppc is the established term 
for ppc32 so
this is very confusing.

Is there any effort to support ppc32 too? I guessing it cannot be too much 
work
to do that as ppc64 is already working?

Any idea if one can cross-compile icedtea from ppc32/amd64 to ppc64?

hmm, yes but configure should bail/error out much earlier when you
ask it build something it cannot. Now one gets the impression that there 
is
just a build failure that needs to be fixed.
