找到：host-m4-1.4.15/lib/stdio.h，然后对stdio.h文件做出如下改动，必要时连同stdio.in.h一起修改：

根据这个补丁文件修改即可，直接修改源代码包，下次编译就不会再提示这个错误了。
3.host-makedevs
/opt/Android/a23androidSRC/lichee/out/linux/common/buildroot/build/host-makedevs/makedevs.c:374:6: error: variable ‘ret’ set but not used [-Werror=unused-but-set-variable]
int ret = EXIT_SUCCESS;
^
cc1: all warnings being treated as errors
直接修改makedevs.c文件：
最后一行，return 0;
修改为：return ret;
