[COMMITTED PATCH] Fix %s that should be %B in several message formats.

That last place was the actual one I had noticed and (knew how to) test.
I'm confused about how the other cases I changed differ from that one.
They pass a bfd * argument to (*_bfd_error_handler) first after the format,
corresponding to a %s in the format.


Thanks,
