The unmodified 2.35 release.  I stick with self-compiled versions to
avoid depending on distributions making their own set of changes.

If the DWARF-5 support depends on specific binutils versions/patches to
work, this should both be documented and detected at configure time.
Having users run into such complete failure as in the Go case is a very
bad user experience IMO.
