@quaresmajose there is a fix staged in core layer master-next already for this. Please cherry-pick that in meantime.

https://lore.kernel.org/openembedded-core/[email protected]/

I am already using the latest tip, for now I have fixed it in my layer but I will also submit a patch for elfutils-devel to remove the unused BUFFER_SIZE.
