In this test we ensure that the worksharing region is running inside a nOS-V task, so we know that we are not using the vanilla OpenMP by accident. We also keep the previous test test/compilers/clang-openmp.nix as-is, so we can check that the compiler injects the nosv library dependency in the final binary on its own.
