RK3588 移植 OpenHarmony-4.0-Beta1 之编译

一、下载与编译

源码下载：

$ repo init -u [email protected]:openharmony/manifest.git -b refs/tags/OpenHarmony-v4.0-Beta1 --no-repo-verify
$ repo sync -c
$ repo forall -c 'git lfs pull'

编译工具链下载：

$ bash build/prebuilts_download.sh

编译：

$ ./build.sh --product-name dayu210

二、编译过程遇到的问题
