This is what I was shooting for as well, the oe-core fix is separate
from the upstream kernel fix. We'll fix our builds first, and then
work for a solution in perf upstream.

My only requirement was that our sed fix still work when kernels start
appearing with it fixed upstream .. something that shouldn't be hard
to do.
