[PATCH] D85474: Add -fbinutils-version= to gate ELF features on the specified binutils version

jhenderson added a comment.

Looks like there's only an `llc` test, but the option is in clang too? Should we have a test there?

Is there any documentation for clang this option needs adding to? Also, this likely deserves a release note, I feel.

It might be helpful to indicate what the default is.
