* libhppa.h (pa_arch): Add pa20.
(hppa_reloc_field_selector_type): Add R_HPPA_NSEL.
(e_nsel): Undefine. Add to hppa_reloc_field_selector_type_alt.
(hppa_field_adjust): Handle e_nsel.
* som.c: Provide default definitions for many new relocs found only
in hpux10 include files.
(som_fixup_formats): Add several new relocs from hpux10.
(som_hppa_howto_table): Add hpux10 relocs.
(som_write_fixups): Handle R_N0SEL and R_N1SEL hpux10 relocs.
Quick stab at handling some of the new hpux10 features.
