* som.c (som_object_setup): More heruistics to detect the
braindamaged HP OSF1 linker.
(setup_sections): Don't forget to free subspace_sections if we get
an error.
(som_slurp_string_table): Allocate strings on this bfd's obstack
rather than directly out of the heap.
(som_slurp_symbol_table): Likewise for the saved copy of the
canonical symbols.
(som_slurp_reloc_table): Likewise for the saved copy of the
canonical relocations. Free the native relocations when we're
done with them.
