I'm ok with this type of solution as well, since this is similar
to what we've had to do with perf in the past (sed and modify versus
patching). I can always patch and fix things in linux-yocto, but then
another other kernel still suffers the issue.

It would be better if folks with this problem also send patches upstream
to allow us to vary the location of awk via a variable, since that would
eventually fix all kernels without needing any modifications .. but that
is a medium term time play, versus doing the sed operation.

If you have a patch to kernel-devsrc in master, feel free to send it
and cc' me, and I can pull it into my queue, test and then send it in
my next pull request.
