my project import grpc 1.47.0, build will fail when cross compile for arm use bazel with --incompatible_enable_cc_toolchain_resolution option

I found out protoc.exe generated for arm, not for host linux x86_64, so I think grpc not recognised it's a cross compilation, grpc may not recognise below option
--incompatible_enable_cc_toolchain_resolution --platforms=@bazel_build_file//platforms:linux_gcc11_aarch64_none_musleabi
it's grpc problem or I need specify other option to make it correct?

Jan, can you take a look please?
@jtattermusch can you take a look?
ask again @yashykt @jtattermusch @drfloob
it's rules_proto problem or bazel has select defect
