Note I reported a similar issue for cc_library here.

If we apply the same fix, then it would just be to remove this line:

OK I looked at this more closely and it looks like this code path is only ever done as a fallback, so it's not actually resulting in warnings in the normal case. The warnings I was seeing my build are due to the cc_library stuff that's built in to bazel and is fixed by bazelbuild/bazel#16414.

Either the fallback should be in place for MacOS and Linux, or for neither. I'm going to close this.
