Bad news, I'm afraid.
On powerpc-darwin8, this fails to bootstrap, with an ICE in libjava (when
trying to build gnu-xml.o).
The backtrace is:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000004

I'll run another build with a patch applied to disable libgcj on
ppc-darwin, and see how that goes. I'll also try to work out which
patch broke it.
