解决办法：不要尝试从虚拟机linux编译windows目录下的源码，一堆莫名奇妙的问题。直接将sdk拷贝到vm分区中编译，问题不再出现。
另外虚拟机性能不够，建议用使用编译命令 make build -j2 | tee build.log，即2个线程编译。

2、报错
ubuntu /bin/sh line1 mkibootargs command not found
make build -j | tee build.log
drivers/Kconfig:59: can't open file "drivers/spi/Kconfig
解决办法：该源码缺少文件。从HiSTBLinuxV100R005C00SPC060中合并缺少的文件即可。
