Error after adding rules_rust to my project

[calebzulawski]

After adding rules_rust to my project, I can no longer generate a compile_commands.json. I get the following error:

FileNotFoundError: [Errno 2] No such file or directory: 'bazel-out/darwin_arm64-opt-exec-ST-d8084f4a0513/bin/external/portable_cc_toolchain+/detail/tools/clang++.sh'

If I examine bazel-out, I find the following file:

bazel-out/darwin_arm64-opt-exec-ST-d57f47055a04/bin/external/portable_cc_toolchain+/detail/tools/clang++.sh

Note that the hash is different. I suspect something with toolchain resolution is making the configuration different.
