Whilst I merged this, we do have a problem here. This change means that
the sstate is locked to the build system architecture.
For example, if you have a 32 bit machine, it can't use any of the
sstate built on a 64 bit machine and vice versa.
I'm not sure what we do about this but its a problem...
Cheers,
Richard
