This patch bothers me a bit. This either is upstream bug or it is not.
So it should be perhaps forwarded upstream and if it is still needed
and accepted that will be good.
otherwise we should drop it.

Yes, that is why I wanted to add the description as it helps with the context
and a specific test. I think we need to clean up a few of the binutils patches
and share with upstream, see what is said, this is one of them.

I obviously saw others I thought we should remove for various reasons :)

Cheers,
