For ordinary relocs, this does not happen for ELF, since for ELF,
bfd_install_relocation uses the "special function" field of the
howto, and does not execute the code that needs to be undone, as long
as the special function does not return bfd_reloc_continue.
It can happen for GOT- and PLT-type relocs the way they are
described in elf32-sh.c as they use bfd_elf_generic_reloc, but it
doesn't matter here since those relocs don't use VAL; see below. */
