问题描述：
在下载了一份安卓13项目的代码后进行make bootimage编译时遇到了下面编译报错：
In file included from /home/bspuser/scode/kernel/msm-4.19/include/uapi/linux/stat.h:5:
In file included from /home/bspuser/scode/kernel/msm-4.19/include/uapi/linux/types.h:14:

make[3]: *** [scripts/Makefile.host:107: scripts/mod/modpost.o] Error 1
make[3]: *** Waiting for unfinished jobs....两种无效解决办法：
先后尝试了两个网上的建议均无法解决上面报错,两个无效建议如下：
1、方法一：（验证无效）
sudo cp -rf kernel/msm-4.14/include/linux /usr/include/x86_64-linux-gnu/
执行此操作后，编译报错仍然存在
2、方法二：（验证无效）
进入kernel代码目录下执行：make headers_install ARCH=arm64 INSTALL_HDR_PATH=/usr
执行此操作后，编译报错仍然存在
最终有效解决方法：
方法三：（验证有效）
在kernel-4.19(或kernel-4.14)代码目录下scripts/mod/Makefile文件中添加一行即可解决此问题
diff --git a/scripts/mod/Makefile b/scripts/mod/Makefile
index e014b2fdd069..cd62ffe2afb4 100644
