/* When generating relocateable output, we don't want to do anything
for a reloc against a globally visible symbol. */
/* i960 COFF is used by VxWorks 5.1. However, VxWorks 5.1 does not
appear to correctly handle a reloc against a symbol defined in the
same object file. It appears to simply discard such relocs, rather
than adding their values into the object file. We handle this here
by converting all relocs against defined symbols into relocs
against the section symbol, when generating a relocateable output
file. */
