Ah, gas doesn't discard that local because it's in a merge section.

Actually, Gnu ld's default is not -X. By default, it only discards local
symbols that are in merge sections (i.e., the only temporary locals that gas
doesn't discard).
To match Gnu ld, I'll need to add that behavior as the new default, and add a
--discard-none option.
