* som.c (bfd_section_from_som_symbol): Renamed from

Browse source 
som_section_from_subspace_index.  Pass in a native SOM symbol.
        For executables, iterate through the sections to find out
        which contains the symbol's address rather than using the
        symbol_info field.  (symbol_info has a different meaning for
        dynamicly linked executables.)
