Yes, this would be nice. I imagine it would look somewhat like the version
for x86. It would be nice to have a generic function which will work for
all arches.

Hmm, I'm a bit suprised by the text increase - Can you provide a more
detailed breakdown of before and after sizes by section?

As I have mentioned before, x86 has an in-RAM increase of only 284 bytes
(0.3 %) with an additional 22424 bytes in .rel.dyn
