The `-[-no]-offloadlib` option is not meant for disabling SDL and I think there is an option to disable SDL. The option is meant for enabling/disabling linking of runtime device library which in case of the chipStar is the `hipspv-spirv64.bc` (which is handled [here](https://github.com/llvm/llvm-project/blob/74687180dde07312521db09c6f6454fe9d1e5662/clang/lib/Driver/ToolChains/HIPSPV.cpp#L203-L208)).
