There is nothing wrong on this, .long   DW.ref.__gxx_personality_v0-.
just becomes a PC relative relocation, which x86-64 has.
As long as the second symbol in the subtraction is dot or dot + constant
or some non-exported symbol in the same fragment, there is nothing
to warn about and it is clear what should be emitted.
