output, and the reloc is against an external symbol, and nothing
has given us any additional addend, the resulting reloc will also
be against the same symbol. In such a case, we don't want to
change anything about the way the reloc is handled, since it will
all be done at final link time. Rather than put special case code
into bfd_perform_relocation, all the reloc types use this howto
function. It just short circuits the reloc if producing
relocatable output against an external symbol. */
