Modern distros ... using binutils 2.15.  ROTFL at that oxymoron.

If you must use binutils 2.16, use software from the same era, and
there will be no problems.  If new software were not allowed to take
advantage of new compiler/assembler features, there would be no point
making new versions of these.
