WARNING: errors encountered while analyzing target '@local_config_cc//:watchos_i386': it will not be built
Most failures are for local_config_cc, but there are also 2 for the protobuf library. They are not directly related to the targets I'm trying to build.

When I run bazel config on these 2 configurations (cafef9f and 9177372), the only difference between the 2 configs is for com.google.devtools.build.lib.analysis.config.CoreOptions.action_env where one config includes the env var and the other doesn't.
I also tried to run bazel cquery --host_action_env=FOO 'somepath(@com_google_protobuf//:descriptor_proto, //path/to/pkg)' but this fails for the same reason.
I'm not sure if I've missed something when upgrading Bazel to 3.7.0, if I'm misusing / misconfiguring something, or if there's an actual issue. Any help would be greatly appreciated!
