    Use TIME_T_MAX and TIME_T_MIN in tst-mktime2.c

    GCC 5.3 compiles

    for (time_t_max = 1; 0 < time_t_max; time_t_max *= 2)
        continue;

    into an infinite loop with -Os.  We can copy TIME_T_MAX and TIME_T_MIN
    from time/mktime.c.

        [BZ #19466]
        * time/tst-mktime2.c (TYPE_SIGNED): New.
        (TYPE_MINIMUM): Likewise.
        (TYPE_MAXIMUM): Likewise.
        (TIME_T_MIN): Likewise.
        (TIME_T_MAX): Likewise.
        (do_test): Initialize time_t_max and time_t_min with TIME_T_MAX
        and TIME_T_MIN.
