that the sections of the referenced symbols (and not the sections
in which the fixup appears) may be subject to relaxation. We'd
still have to check the section in which the fixup appears, because
we want to do some simplifications in debugging info that might
break in real code.
Using the infrastructure in write.c to simplify subtraction fixups
would enable us to remove a lot of code from tc_gen_reloc(), but
this is simpler, faster, and produces almost the same effect.
Also, in the macros above, we can't check whether the fixup is in a
debugging section or not, so we have to use this for now. */
