Sorry for the disturbance.

I proposed this patch set:
https://lore.kernel.org/buildroot/20220610165441.84812-1-flaniel@linux.microsoft.com/
to fix the build failures.
As pointed above, I am also not able to reproduce locally and I do not have 
access to an autobuilder setup (or I do not know how I can mimic one) to 
investigate on it.

Do you think the above patch can do the trick?
If not, is it possible to deploy locally an autobuilder to check if I can 
reproduce the problem and propose a correct patch?
