The profiling "built into bitbake" is using python's own internal
performance code using cprofile and pstats so those are deterministic
profiles with exact call counts.

perf is statistical profiler so it will show information differently as
averages.

Both have a time and a place and it could be interesting, just flagging
the difference (and that we're using python's own profiling tooling for
this).
