Update to ns32k support, from Ian Dall (dall@hfrd.dsto.gov.au).
* aout-ns32k.c: Add declarations that were in aout-ns32k.h, change
declarations to traditional form.
(MY_reloc_howto, MY_put_reloc): Change from macro to function.
(ns32k_relocate_contents): New function.
* aout-ns32k.h: Remove.
* cpu-ns32k.c: Add declarations that were in aout-ns32k.h, change
declarations to traditional form.
(ns32k_final_link_relocate): Call ns32k_relocate_contents.
* netbsd532.c: Reformat to standards, add copyright notice.
(ARCH): Don't define.
(aout-ns32k.h): Don't include.
* pc532-mach.c: Ditto.
