linux 下 scons 报错

第一次用 rtt，用的最新 github 上 checkout 的，用了两个linux发行版都会在这里报错。但在 windows 下就能正常跑起来。用的 qemu-vexpress-a9。

但看上去像是系统环境的问题？
这个 `__USE_XOPEN2K8` 是什么条件才会开起来呢？我试了下自己强行 define 也过不去。

查了下是在 struct_stat.h 里定义的，不知道有没有找错地方。
```c
# ifdef __USE_XOPEN2K8
    /* Nanosecond resolution timestamps are stored in a format
       equivalent to 'struct timespec'.  This is the type used
       whenever possible but the Unix namespace rules do not allow the
       identifier 'timespec' to appear in the <sys/stat.h> header.
       Therefore we have to handle the use of this header in strictly
       standard-compliant sources special.  */
    struct timespec st_atim;		/* Time of last access.  */
    struct timespec st_mtim;		/* Time of last modification.  */
    struct timespec st_ctim;		/* Time of last status change.  */
#  define st_atime st_atim.tv_sec	/* Backward compatibility.  */
#  define st_mtime st_mtim.tv_sec
#  define st_ctime st_ctim.tv_sec
# else
    __time_t st_atime;			/* Time of last access.  */
    __syscall_ulong_t st_atimensec;	/* Nscecs of last access.  */
    __time_t st_mtime;			/* Time of last modification.  */
    __syscall_ulong_t st_mtimensec;	/* Nsecs of last modification.  */
    __time_t st_ctime;			/* Time of last status change.  */
    __syscall_ulong_t st_ctimensec;	/* Nsecs of last status change.  */
# endif
```
