The test was successful, but I don't see a good reason to use this approach for now. |

Ok, actually we might want to use this in BPF CI. The problem with current implementation is that many copies of the same GCC build are cached, because caches between pull requests are separate. So using a pre-built release is much more reasonable. I am going to restore and update this change to use latest release at https://github.com/theihor/gcc-bpf |
Running libbpf/ci/build-bpf-gcc action builds GCC from latest source snapshot and caches the output with actions/cache. Because of actions/cache rules, caches between pull requests are independent. This results in cache being full of identical GCC builds, which interferes with caching actually useful things. To avoid this, and also to not re-build GCC all the time, download a pre-built GCC and use it. The "build release" job is set up in an independent repository, publishing artifacts as a release tag.
