build failed with bazel 4.0, Arch Linux

[blessingsi]

I tried to build with bazel 4.0.0, and got an error:

 in proto_lang_toolchain rule @com_google_protobuf//:cc_toolchain: '@com_google_protobuf//:cc_toolchain' does not have mandatory provider 'ProtoInfo'.

system, archlinux:

Linux 5.10.13-arch1-2 #1 SMP PREEMPT Sat, 06 Feb 2021 11:07:29 +0000 x86_64 GNU/Linux

bazel version:

Build label: 4.0.0
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Thu Jan 21 14:04:24 2021 (1611237864)
Build timestamp: 1611237864
Build timestamp as int: 1611237864

I found bazelbuild/bazel#12887, and try to upgrade protobuf to v13.0, but there are some other dependency issues.

I've addressed this issue internally and will update with the fix in the next day or two.
