Actually - thinking about it further ... why should it matter that it is a
note section that is being relocated ?  Surely the same logic should apply
to any ifunc-targeted relocation in a non-alloc section.  For example, I
wonder if your patch would actually work for debug sections as well ? 
(Rather than the current option of just silently ignoring the reloc).
