In the light of the discussion that has taken place, we have found a
solution that apparently matches your use case, by using the existing
Buildroot options. Therefore, I've marked your patch as Rejected in
patchwork. If you disagree, do not hesitate to re-send an updated
version with an extended justification.

Thanks a lot!
