[Ubuntu 18.04] zsv linked GLIBC version issue

zsv did not work after installing the .deb packages.

As these binaries are built on Ubuntu 20.04 so this issue is expected for the versions lower than 20.04 (where GLIBC version is not supported).

To support Ubuntu 18.04, the runner should be the same.
However, the Ubuntu 18.04 runner has been deprecated.

One solution could be to generate a statically linked binary to resolve this issue.
Another could be to build binaries on Docker containers and distribute those.

In addition, the minimum supported version of the target OS for the prebuilt binaries should properly be documented in the README in case the static linkage is not possible.

Thanks!

[liquidaty]

Thank you. I think we should make it a static build. Could you make those changes?

[iamazeem]

Sure, I'll try to generate static builds for the supported Linux variants.

However, it might not be possible for macOS, and we'll have to resort to -mmacosx-version-min compiler flag to specify the lowest supported version e.g. -mmacosx-version-min=10.15, if it comes to that. 🤔

@liquidaty: Was this reported by any other users or experienced internally?
I was planning to work on it by building on Ubuntu 18.04 container.
But, if it's not an issue, this can simply be closed.
