Yes.  It will also happen automatically if you run configure with
--enable-maintainer-mode, although in that case you need to have the
correct versions of autoconf and automake in your PATH.

Add the architecture in bfd/archures.c.  Follow the existing
examples.  You edit comments in archures.c which get turned into
definitions in bfd.h.

Add those names to bfd/reloc.c.  Follow the existing examples.

Yes.
