That's not quite true. ELF is a bug, yes, and I continue to maintain
that our interests are best served by planning to move on from it when
that becomes feasible. But there are various things that can be done
to work around the worst problems. Since adopting something else
(Portable Interface for eXecutable Insertion and Embedding? Generic
OBject LINking?) would be extremely expensive, especially in the
absence of a ready alternative to binutils, we should take these steps
where they're feasible.
