[clang] [Driver] Fix Tests when specifying unwindlib (PR #144582)

[Sam Elliott via cfe-commits]

https://github.com/lenary created https://github.com/llvm/llvm-project/pull/144582

The openmp-offload-amdgpu-runtime-2 bot specifies default rtlib of compiler-rt, but default unwindlib of libgcc. Change the tests to accept that there may be `"--as-needed" "-lgcc_s" "--no-as-needed"` between `libclang_rt.builtins.a` and `-lc`.

Relates to #121830

The openmp-offload-amdgpu-runtime-2 bot specifies default rtlib of
compiler-rt, but default unwindlib of libgcc. Change the tests to accept
that there may be `"--as-needed" "-lgcc_s" "--no-as-needed"` between
`libclang_rt.builtins.a` and `-lc`.
