I think my idea here was that I didn't want to create a common section
which was attached to dynobj, because dynobj is a real BFD which might
have its own local .sbss symbols, and using that section for common
symbols would confuse something.  Or something.

Perhaps someone with access to the Red Hat internal tree could look at
the CVS log entry for that change.  Since it doesn't appear to be part
of any other work I was doing, I wouldn't be surprised if there is a
PR number attached to it.
