Bazel toolchain doesn't correctly figure out LLVM name for Suse distributions

[pgagala]

🐞 Bug Report

Description

It isn't possible to install Prysm from the source (https://docs.prylabs.network/docs/install/install-with-bazel)
on Suse Linux distributions (leap, tumbleweed).
Bazel toolchain (https://github.com/grailbio/bazel-toolchain) currently doesn't correctly figure out the LLVM name for Suse distributions.

Has this worked before in a previous version?

Rather not but I didn't check all previous versions of the Bazel toolchain.

🔬 Minimal Reproduction

Precondition: Operating system - any of Suse distribution
Type bazel build //beacon-chain:beacon-chain --config=release in main Prysm folder.

🔥 Error

Following PR fix that issue: bazel-contrib/toolchains_llvm#86 (waiting for merged that and then the issue will be closed)

[pgagala]

PR merged. 0.6 release from https://github.com/grailbio/bazel-toolchain/releases/tag/0.6 should be used in a system in order to fix that issue

This is blocked by updating bazel to v4.0.0 then we can update to 0.6 of that toolchain.

[rkapka]

This is unblocked now, right @prestonvanloon ?

[prestonvanloon]

This is fixed now that we have switched to the zig based toolchain, which does a much better job of loading the c++ compiler. Closed by #12135
