Isn't a linker allowed to discard symbols if nothing uses them?

The symbols referenced by the relocation are only ever called via a weak 
reference from the unwinding library. The use of the routine is implicitly 
encoded in the unwinding tables.

Yes. The ABI defines and requires the use of a zero reloc (R_ARM_NONE).
