Using static kcl binary crashes on musl-based Alpine

[BenediktFloeser]

Bug Report

We noticed that pulling the kcl cli binary from the releases and putting it inside an Alpine image results in an error. A call to kcl itself correctly prints a help message but doing something like kcl somefile.k results in an error concerning a shared library. I assume kcl depends on some libc component which leads to this issue.

I am aware that there is an open issue concerning a musl build of kcl but IMHO a static build should suffice for this use case.

1. Minimal reproduce step (Required)

• Create an Alpine container/VM.
• Put the latest kcl binary and a sample kcl file inside.
• Run kcl sample.k

2. What did you expect to see? (Required)

I expected to see the resulting YAML

3. What did you see instead (Required)
