I am working towards bootstrapping powerpc-darwin8 (-O0 -fPIC -fno-common 
-no-integrated-as), but am running into miscompilations.  I'm able to 
get 60% into stage 2 without complaints from the system assembler, so 
that's a good sign.

In particular, tblgen is crashing and so is unittests/ADTTests.

http://llvm.org/bugs/show_bug.cgi?id=15901

Bootstrapping is a long road ahead.
