That was it. I can now reliably build, up to the pdump step, with a
native-compiled macroexp.eln, which wasn't the case previously. Dumping
sometimes gets an error here:

dump_native_comp_unit (struct dump_context *ctx,
                       struct Lisp_Native_Comp_Unit *comp_u)
{
  if (!CONSP (comp_u->file))
      error ("trying to dump non fixed-up eln file");

It might be dependent on ASLR because it works reliably in LLDB but not
outside. That's the next step then.
