What is left to submit / get working in the mainline w/respect to the

varargs are broken because of GCC infrastructure problems for subregs
of simd types on hard registers. I suggested an approach, but Jan
Hubicka had another idea which he hasn't implemented. I may kludge it
on the e500 branch, since there doesn't seem to be an agreement on how
to fix GCC.
long doubles are broken on purpose on mainline. The ABI specifies 128
bit long doubles, but I have left them as 64 bits since there are no
emulation bits for powerpc-eabi*.
vector types going on varargs, in the named section of the arguments,
are supposed to be split. They currently are not.
Everything above I'm "working on".
Finally, there are a mess of multilibs to be built by default. I have
a patch, but I'm still testing the multilibs before I commit to
mainline.
