飞牛 1.0.0 版本，编译一个基本的 C 程序，都找不到 stdio.h。
catboy@XXX:~$ gcc all-disks.c
all-disks.c:1:10: fatal error: stdio.h: No such file or directory

compilation terminated.
尝试安装 build-essential 包，提示 C 库的依赖不满足。
catboy@XXX:~$ sudo apt install build-essential

请问飞牛的技术人员：
- 飞牛是否维护了自己的 glibc，或是内核固定了某一版本的 glibc？
- 我能否安全地安装
libc6-dev？该操作是否会破坏飞牛的组件依赖？
- 如果不能自行安装，飞牛是否提供交叉编译工具链？亦或是其他的 C 开发途径？
