64bit multilib is not supported yet so this is not excepted to work yet.

I'd like to point out that as documented extensively in bug report 22082, 64-bit
compilation *does* work on powerpc-darwin-8 with gcc-4.0.0, and it doesn't now
work on the mainline or the 4.0 branch.  Mike Stump proposed a fix in

http://gcc.gnu.org/ml/gcc/2005-06/msg00615.html

but then mainline couldn't find the installed libgcc_s_ppc64, as documented in

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22110

So while there's no discussion in *this* PR of *any* of these issues, if you
follow these links you'll find useful information
