We don't have 64-bit atomics on powerpc, but we don't really need them.

We don't have 64-bit atomics on powerpc, but we don't really need them.
So don't provide atomic64_cmpxchg() on powerpc and on other architectures
make its implementation similar to atomic64_xchg().
This makes the tree build again on macppc.
