Hi Richard,

> include/coff/
> 	* xcoff.h (XCOFF_ALLOCATED): New flag.
> 
> bfd/
> 	* xcofflink.c (xcoff_mark): When walking the relocations,
> 	only mark the target symbol or the target section, not both.
> 	(xcoff_final_definition_p): New function.
> 	(xcoff_keep_symbol_p): Use it to check whether an external XCOFF
> 	symbol is a valid definition of the associated output symbol.
> 	Use XCOFF_ALLOCATED to stop the same hash table entry having
> 	two output symbols.
> 	(bfd_xcoff_size_dynamic_sections): Set XCOFF_ALLOCATED when
> 	keeping a symbol.
> 	(xcoff_link_input_bfd): Use xcoff_final_definition_p.
