* som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and

        HAS_RELOC based on the object's magic number.
        (make_unique_section): Delete function.  BFD and its users are
        prepared to handle multiple sections with the same name.
        (setup_sections): Allocate space on the BFD's obstack to hold
        section names.  Use bfd_make_setion_anyway rather than the
        obsolete make_unique_section.
        (som_prep_headers): Choose the correct SOM magic number based
        on the BFD's flags.
        (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
