If you are curious and want to test the above fix on a non ARM system
then apply the attached patch in this mail, it makes any Shark system
use the atomic of zero instead of llvm, this makes it possible to test
the atomic workaround on X86 and PPC systems. The reason why this works
are because the workaround itself are platform independent.
