It seems __bss_end__ is not a true convention for all toolchains, at least not for PPC. Using _end for standalone programs might be the simplest way to fix this problem.
One of the other choices may be writing a linker script to provide __bss_end__ for PPC.

Not sure if this is the best solution, but I think this could fix Heiko's problem.
