How is "breaks with binutils before version 2.23" not clear enough? It
will break regardless of whether distro shipped v2.21 or you built
v2.21. I'm _not_ creating a custom binutils with my own patches
specifically to trigger this issue, it's stock binutils, as stock as you
can get it.

Do you really want me to say in the commit message "to reproduce, first
compile binutils-2.21 from source, then try to build the kernel with
it"? Including this information would make sense only if the problem
wasn't with stock binutils, but only with some specific distro's patched
version. _Then_ it would make sense to say something like "binutils
package v-xxx shipped with OpenSUSE v-yyy was broken, this commit works
around it". This is a problem with _any_ binutils-2.21, there's nothing
special about how you need to build it.
