>         * Makefile.in: Regenerate.

BTW: I should also mention that I did a grep of all .o files in bfd/,
and compared that with the list of include directives in the Makefile.
Only rs6000-core.o showed up as not having its assocated .Plo include.
So, at least for ppc-aix, we should be OK once this patch is installed.
