Comment(by jeremyhu@…):

 cctools now uses llvm-2.9 on Tiger/ppc (r92277)

 I saw this issue with Leopard/ppc on llvm-3.1 which is why llvm-3.1's
 supported archs are intel.

 I do not see this issue with Leopard/ppc on llvm-3.0.

 Do you see this if you do build llvm-3.0 as:

 {{{
 sudo port -v install ld64 cctools
 sudo port -v install llvm-3.0 configure.compiler=apple-gcc-4.2
 }}}

 I'm wondering if perhaps the newer linker is smarter about reordering to
 address this issue.  That might explain why 3.0 built on Leopard.

 Additionally, try changing the optimization level from -O2 to -Os
