* ecoff.c (ecoff_set_symbol_info): Add new parameter weak. If set, set BSF_WEAK in symbol. Change all callers. (ecoff_get_extr): Set weakext based on BSF_WEAK. (ecoff_link_add_externals): If weakext is set, pass BSF_WEAK to _bfd_generic_link_add_one_symbol. (ecoff_indirect_link_order): Check that the section tdata relocs are not NULL before using them.
