In general you can answer what we think is best by checking the llvm-gcc
sources from llvm, and in this case, we are using:
/* { dg-options -fnext-runtime -fno-constant-cfstrings } */
/* { dg-do compile { target powerpc

I've filed radr://7457013 for libSystem (aka libm on 10.6) to improve the
accuracy of ___divdc3. If that were fixed, then having -lm or not wouldn't
matter.

I suspect the other case is simply:
