I'm not being able to apply this specific patch:

I'm checking what is this, perhaps I'm using a more recent
perf-tools-next/perf-tools-next with changes to that
tools/perf/tests/workloads/Build file...

Yeah, we need to rebase on top of what we have in
perf-tools-next/perf-tools-next, probably something minor.
