Hi Ross,
Here is the background of this:
Initially we found this issue, when we are trying to build the Arm FVP for
openbmc, as you can see from the discussion here:
https://gerrit.openbmc.org/c/openbmc/openbmc/+/70070/comment/4a963c24_75b11840/

So thanks to the kind help from Patrick Williams (cc'ed here), he proposed
to try this fix:

> diff --git a/poky/meta/recipes-kernel/perf/perf.bb
> b/poky/meta/recipes-kernel/perf/perf.bb
> index 11fa917649..d39265367b 100644
> --- a/poky/meta/recipes-kernel/perf/perf.bb

 # needed for building the tools/perf Python bindings
> -inherit_defer ${@bb.utils.contains('PACKAGECONFIG', 'python',
> 'python3targetconfig', '', d)}
> +inherit_defer ${@bb.utils.contains('PACKAGECONFIG', 'python',
> 'setuptools3-base python3targetconfig', '', d)}


However, it is still not working. I added a workaround with this patch:
https://gerrit.openbmc.org/c/openbmc/openbmc/+/71017

Still, Patrick thinks that this should not be the case, and the proper fix
should be done via OpenEmbedded.

Currently we are not sure how to fix this properly and don't have any idea.
Much appreciated if you or anyone have any idea on this!

Thank you,
Sheng
