Fine - and thanks for the reminder (in private mail).

I agree with the intent of this patch.
But as it is my experience that most people use
CROSS_COMPILE on the commandline and not as an
environmnet variable most will not benefit from this patch.

We should as a minimum document this use of decodecode where we
document its usage today (oops-tracing.txt).

We could also make it a Makefile target thus it is a bit
more natural to supply the typical Makefile parameters?

Please rework one way or the other.
