--- Comment #10 from Iain Sandoe <iains at gcc dot gnu.org> ---
sorry I fixed this months ago locally..
 I will push a patch to fix ASAP.

note that there are 4 bootstrap breakers on PPC (trunk)
1. this
2. libcc1 (same fail as x86)
3. libiberty needs some options massage to build PIC properly (will also break
i686-darwin*)
4. libada is currently looking for __environ and needs a modification to the
makefile, affects at least 10.5, 10.6
