Yes, definitely.

So let us switch to a whitelist approach: the only architectures *not*
needing far branches are:
- i386 (32-bit displacement but currently not supported anyway
        for no-threading);
- x86_64 with some luck (32-bit displacements which will be enough
  in practice);
- m68k -- 32-bit displacements, working well form me but with
          no-threading poke being broken for unknown reasons, maybe
          the same as powerpc32.

A little sad.  Making the temporary change.
