Release builds for older Linux versions

My university cluster servers are still on Rocky Linux 8.10. When I try to run the release builds I get errors like the following:

./llama-cli: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by ./llama-cli)
./llama-cli: /lib64/libcurl.so.4: no version information available (required by ./llama-cli)
./llama-cli: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./llama-cli)
./llama-cli: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./llama-cli)
./llama-cli: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by ./llama-cli)
./llama-cli: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by ./llama-cli)
./llama-cli: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by ./llama-cli)
./llama-cli: /lib64/libstdc++.so.6: version `CXXABI_1.3.13' not found (required by ./llama-cli)
./llama-cli: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./llama-cli)

This is a common problem when executables are built on a more recent machine than the one where you're trying to run it.

I've managed to put together a docker image capable of building for Rocky Linux 8.10, including Vulkan support. Would there be any interest in getting this upstreamed to improve backwards compatibility of the official builds?

It was already discussed before. Basically we stick with ubuntu 22.04 as lowest requirement because:

• The project fails to build on CI with ubuntu 20, it requires too much efforts to make the build passes
• Ubuntu 20 runtime is deprecated on github action

Ah that makes sense. So even if we replaced the current CI with my Rocky Linux 8.10 Dockerfile, it likely isn't supported by GH actions.
