    Fix nvptx-specific '-foffload-options' syntax in 'libgomp.c/reverse-offload-sm30.c'
    
    That is, '-mptx=_' is only valid in '-foffload-options=nvptx-none', too.
    
    Fix test case added in recent
    commit r13-2625-g6b43f556f392a7165582aca36a19fe7389d995b2 "nvptx/mkoffload.cc:
    Warn instead of error when reverse offload is not possible".

            '-foffload-options' syntax.
    
    (cherry picked from commit b61796663ba1fe8fb83203829398f3f89ec212b7)
