Describe the bug

参考 https://github.com/RT-Thread/rt-thread/issues/9812#issuecomment-2664977960，

用 https://download.rt-thread.org/download/rt-smart/toolchains/riscv64gc-linux-musleabi_for_x86_64-pc-linux-gnu_latest.tar.bz2 这个工具链做了一个 helloworld 运行后报错

#include "stdio.h"

void main()
{
	printf("Hello world!\n");
}

静态链接：

~/ws/bin/rtt-tools-smart/riscv64gc-linux-musleabi_for_x86_64-pc-linux-gnu/bin/riscv64-unknown-linux-musl-gcc -static ./hello.c -o ./hello

bsp/cvitek 下制作 smart 版本或者 bsp/qemu-virt64-riscv 制作 smart 版本，启动后运行 hello，报错类似如下：

/ # ./hello

这个最新版可能不是真的最新版

[BernardXiong]

这个后面固定一个版本吧，也就是说musl gcc正式发一个版本出来

怎么说呢，这个问题我去年 12 月底就报了，到现在也没有看到解决的希望。see #9812 (comment)

这个是需要先验证好一个版本，然后出一个带版本的工具链出来，还是先确认好没问题的才是
