I am planning to add arch-specific implementations for m68k and sh in the near
future. From the current build logs in Debian, it seems that the JVM is actually
hanging on these architectures from time to time and I think this could probably
be related to atomic_copy64 actually not being 100% atomic. I already added the
one for PowerPCSPE.
It's also interesting that there is no implementation for 32-Bit MIPS either.
