    Avoid -latomic for amdgcn offloading
    
    libatomic isn't built for amdgcn but reduction-16.c adds it
    via -foffload=-latomic when offloading for nvptx is enabled.
    The following avoids linker errors when offloading to amdgcn is enabled
    as well.

            * testsuite/libgomp.c-c++-common/reduction-16.c: Use -latomic
            only on nvptx-none.
