Technically this bug is invalid (undefined is undefined, not consistent). ARM
maintainers may want to disallow tail/sibling calls to possibly weak targets.
The ABI is inconsistent itself, btw, as
weak_fn ();
beahaves different than
*(&weak_fn) ();
as I presume the linker cannot do anything for indirect calls to weak
functions.
