The comment at the beginning of dw2_asm_output_delta seems relevant.  Why
does your implementation work for Darwin, when that comment suggests it

It's already kludgy; this should have been handled better when the target
hook for eh_frame_section was added.

One option would be to terminate it only if targetm.eh_frame_section is
still set to the default function.  Speaking of which, it probably makes
sense to have two different default functions, depending on whether or not
