Considering the already-known quirkiness of ELF handling by other CUDA tools, I would not hold my breath for objcopy keeping CUDA tools/runtime/driver happy, either.

That's another point for growing our own ability to deal with NVIDIA GPU binaries in LLD and other LLVM's binary utilities. Everything else will require playing this endless game of whack-a-mole chasing version-dependent quirks in NVIDIA's tools.
