env:

• llvm version:14.x(14.0.6) i can use -mllvm bcf -mllvm fca -mllvm sub normally. but i can not use -mllvm -sobf . cmd:
• $clangPath/clang -isysroot xcrun --show-sdk-path -arch arm64 -mllvm -sobf -emit-llvm -S hello_ollvm.c -o hello_ollvm_sobf.ll
• $clangPath/clang -isysroot xcrun --show-sdk-path -arch arm64 -emit-llvm -S hello_ollvm.c -o hello_ollvm.ll the hello_ollvm_sobf.ll and hello_ollvm.ll are exactly the same.

not work + 1.In my case it build failed using the toolchains build from version 14.x, not works for all -mllvm options when build for hook like halabi.
