Sure, but [1] (turn on multithreading for xz) hasn't been
accepted, and effectively appears to be dead. _if_ that goes in,
I absolutely agree that the toolchain should be the same as the
SDK. If it _doesn't_ go in, I'd say really that the SDK should be
put back to bz2 to be consistent with the toolchain :)
