Thanks a lot for doing this, this is indeed an important change to be
done ... also due security reasons.

Yes, you likely needs a rmic-native variant.

I am very busy now and won't have bandwidth to help on this, am sorry.

One side note though ... you might want, before, clean old versions of
the recipe and rework it so in the process you gain more intimacy of
the build process ... and helps to provide a nicer base of work as
well.
