suitesparse FTBFS on loong64 and sparc64 due a packaging issue with an implicit CUDA
dependency. The failing build step is actually at dpkg-shlibdeps which fails since it
cannot find the lib*_cuda.so shared libraries anywhere [1][2]:
This is not surprising since the corresponding lib*_cuda.so shared libraries are being
deleted in debian/rules [3]. However, I have no clue why this affects loong64 and sparc64
only.
