(class process_target): Add the target op. (join_inferior): Update the macro. Update the derived classes and callers below. * linux-low.cc (linux_target_ops): Update. (linux_join): Turn into ... (linux_process_target::join): ... this. * linux-low.h (class linux_process_target): Update. * lynx-low.cc (lynx_target_ops): Update. (lynx_join): Turn into ...
