From: Jeff Law <law@redhat.com>

Subject: 	* somread.c (som_symtab_read): Handle dynamic relocation for
 both 	text and data symbols. 	(som_symfile_offsets): If objfile is a shared
 library, then get 	text and data offsets from the shared library
 structures. 	* somsolib.c (som_solib_add): Copy the bfd pointer from the 
 objfile rather than reopening the file again. 	(som_solib_section_offsets):
 New function. 	* somsolib.h (som_solib_section_offsets): Declare.
