When we build llvm with this cmd
```
cmake ../llvm -G Ninja -DLLVM_DEFAULT_TARGET_TRIPLE=aarch64-linux-gnu -DLLVM_USE_LINKER=lld -DLLVM_ENABLE_RUNTIMES="compiler-rt;libunwind" -DLLVM_ENABLE_PROJECTS="mlir;clang;clang-tools-extra;lld" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=RelWithDebInfo
```
It builds successfully, while if we try do something like
```
./bin/clang --rtlib=compiler-rt hello.c
```
Something wrong happens
```
/usr/bin/aarch64-linux-gnu-ld: cannot find <PATH>/build-aarch64/lib/clang/19/lib/linux/libclang_rt.builtins-aarch64.a: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
