If that reference is indeed the spec, then this change needs to be made.
But before I put it in I am wondering whether there might be any gotchas,
i.e. existing binaries that depend on the erroneous behavior.  If so, 
we should do some versioning.

>Description:
When __cxa_finalize is called with a NULL DSO handle, it 
should run *all* cleanups; instead it runs none of the
cleanups.

See:

for the specification of this function.

I don't know.  Weak undefined references to __dso_handle might be a
problem.  Just make the change.
