背景：

1.克隆oh 的llvm代码然后预下载，然后先编译生成arm版本的目标，然后把clang18替换clang15，在clang18的基础上同步oh clang15的修改。结果编译third_party/musl的时候，报不识别编译选项，结果如下：

摘要：

[OHOS ERROR] clang: error: unsupported option '-mfloat-abi=' for target 'x86_64-unknown-linux-gnu'

具体如下：

[OHOS ERROR] Solution:  Please check the compile log at out/{compiling product}/build.log, If you could analyze build logs.
[OHOS ERROR]            Or you can try the following steps to solve this problem:
[OHOS ERROR]              1. cd to OHOS root path
[OHOS ERROR]              2. run 'hb clean --all' or 'rm -rf out build/resources/args/*.json'.
[OHOS ERROR]              3. repo sync
[OHOS ERROR]              4. repo forall -c 'git lfs pull'
[OHOS ERROR]              5. bash build/prebuilts_download.sh
[OHOS ERROR]              6. rebuild your product or component
[OHOS ERROR]              7. check if any environment variables required by the building process are not set in build/compile_env_allowlist.json
