Yeah it could. But is it worth doing? Even if it was done it would have
no effect on the build downstream consumers do, unless they
specifically take that value and pass it to configure.

So I'm somewhat on the fence about this as it would be yet annother
change which would needed to be done as part of the CPU patching (and
reverted once the next dev-cycle starts). A lot of churn for little
gain.

It feels like it's not really worth doing. YMMV.

Thanks,
Severin
