emerge .log

When emerging sci-libs/rocRAND on a clang profile with llvm 19 it fails because of error: no member named 'par_unseq' in namespace 'std::execution.

Adding -fexperimental-library fixes the issue as mentioned in https://github.com/llvm/llvm-project/issues/65125

std::exectuion::par_unseq requires c++17 iirc.
