* alpha-osf1-tdep.c (alpha_osf1_init_abi): Unfortunately,

procfs appears to be broken when debugging on multi-processor
        machines. So enable software single stepping in order to avoid
        using the procfs interface to do next/step operations, using
        internal breakpoints instead.

        * infrun.c (handle_inferior_event): Readjust the stop_pc by
        DECR_PC_AFTER_BREAK when hitting a single step breakpoint, to
        make this pc address equal to the value it would have if the
        system stepping capability was used. Also set a new flag used
        to ensure that we don't readjust the PC one more time later.

        * breakpoint.c (bpstat_stop_status): Do not adjust the PC
        address by DECR_PC_AFTER_BREAK when software single step is
        in use for this architecture, as this has already been taken
        care of in handle_inferior_event().
