就一个简单的 c 程序:
```c
#include <stdio.h>
int main()
{
printf("Hello, World\n");
}
```
使用如下命令编译：
```
riscv64-linux-gnu-gcc --static hello.c -o hello_riscv64
```
居然可以直接运行
```
> ./hello_riscv64
Hello, World
```
使用 qemu 也能运行：
```
> qemu-riscv64-static hello_riscv64
Hello, World
```
readelf 结果：
```
> readelf -h hello_riscv64
