Thanks.  This seems to work well:

#define ENCODE_SECTION_INFO(DECL)       encode_section_info(DECL)

#define SYMBOL_REF_EXTERNAL SYMBOL_REF_FLAG

void
encode_section_info (decl)
     tree decl;
{
  enum tree_code code = TREE_CODE (decl);
  if (code == VAR_DECL || code == FUNCTION_DECL)
    SYMBOL_REF_EXTERNAL (XEXP (DECL_RTL (decl), 0)) = !TREE_STATIC (decl);
}
