 Hmm, you can't mean we should keep global symbols from dropped sections 
(be it section or ordinary symbols), can you?

 We're dropping this symbol because it does not belong to any section 
being output, not because it's global or not.  If it wasn't absolute, but 
its section was dropped, it would be (correctly) dropped as well.  
Likewise if it was local and absolute, it would be (incorrectly) dropped 
too -- this is fixed by my change just as for global absolute symbols.

 I'm confused, sorry.
