[md]### 【问题描述】

1. 【介绍问题现象和发生的背景】
我按照官方文档介绍安装并通过gitee ssh下载好了OpenHarmony源码3.1.7版本，hb工具也已经正常安装，并且也有执行bash build/prebuilts_downloads.sh，然后hb set选择qemu-arm-linux，然后报错缺失文件：

2. 【相关的代码操作】

repo下载完源码后，hb set选择qemu-arm-linux，然后执行hb build -f;
3. 运行结果、错误截图

4. 【我尝试过的解决方法和结果】

如果是hb set 选择的是qemu_small_system_demo，能够正常仿真运行liteos-a的内核，但是选择qemu-arm-linux就编译不过去，然后我对比发现路径OpenHarmony3_1_7/vendor/ohemu/qemu_arm_linux_min目录也缺少了较多文件，例如hals层的支持（不知道是不是正常的，我看4.0源码也是一样）

5. 【我想要达到的结果】

希望各位大佬帮忙看看，是不是openHarmony已经放弃支持qemu的linux内核仿真，是不是还需要下载什么文件？才能编译qemu-arm-linux。我最终是编译完，需要通过qemu仿真运行的。

高度怀疑是环境问题，下载的是什么时候的代码？看起来只有分支名~~
