错误一：

　　1.解决参考：http://blog.csdn.net/u010445505/article/details/39299855

　　2.下载得到文件__gnu_mcount_nc_patch.patch.gz后，使用命令：gzip  -dc  __gnu_mcount_nc_patch.patch.gz | patch -p1，再次编译，搞定

错误二：

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at kernel/timeconst.pl line 373.

　　1.问题分析：defined不能用

　　2.问题解决：将kernel/timeconst.pl第373行的defined去掉，即改为：
