Flags passed to nvcc for host configuration don't honor cfg

The flags passed to the host compilation portion of nvcc don't honor the bazel configured toolchain flags.

Notably -g doesn't get propagated to the flags passed to nvcc when building with -c dbg and as a result no symbols are found.

Maybe a search path issue? For me, I need to use dir bazel-rules_cuda for symbol to work image

No, it's definitely missing the symbols, I have to add -g to host_copts to get it to work. This is specifically with the grailbio llvm 14 compiler as the host compiler so it may be down to some interaction with those rules.

Can you provide a repro? I might dig into it once I have time.

I'll have to try to find some time to isolate a reproducer, its within a reasonably complex build setup with pybind extensions so it's not easy to pull out straight away
