While the solution that Ian suggested may be the "right thing", it's clearly not what BFD ld nor gold implement and it's unlikely that their implementation is going to change. Since there is code out there relying on this behavior, it'd be useful for lld to support it.

As written this is just duplicating a bug and we should not do it.

It is entirely possible we just have another case where lld gets
confused about a symbol being absolute or not. Can you provide the full
original code in musl that fails with lld?

Cheers,
