Thanks for the link.  That may be useful.  It might be portable on UNIX 
flavors but probably not on Windows linkers.  Also I think when linking 
targets the granularity for including symbols is the object file level, 
so by linking every symbol into a single object then any program that 
uses one symbol will get the whole thing.  However I'll have to 
investigate what the -r option does.

I've added the information to the corresponding feature request:
