Question: CI configuration?

[xfbs]

Hey!

So, I made the PR for #512. I saw that the CI is testing Windows and macOS targets. I fixed my PR to make those checks pass, however that made me think: does it even make sense that we test for Windows and macOS targets? In my understanding, unlike coreutils/binutils, the util-linux tools are all specific to Linux (eg: make syscalls that are Linux-only) and are not designed to be portable. Checking that they compile on Windows/macOS does not add much value (usually just means we need cfg blocks to disable things).

I feel like checking if they will build on macOS and Windows adds little value. However, what might add more value is having checks for different architectures on Linux, specifically:

• x86_64-unknown-linux-gnu
• x86_64-unknown-linux-musl
• riscv64gc-unknown-linux-gnu
• riscv64gc-unknown-linux-musl
• aarch64-unknown-linux-gnu
• aarch64-unknown-linux-musl
• i686-unknown-linux-gnu (maybe, if we care about 32-bit)
• i686-unknown-linux-musl (maybe, if we care about 32-bit)

I feel like we should make sure that the tools compile and work on these.

What is your take on this?
