Add musl support on linux arm servers

[sureshg]

Using native-image-musl: true on arm servers causing errors (ubuntu-22.04-arm). Is static build (using musl) on arm supported?

Hi @sureshg,
Thanks for the ticket. Static images are currently only supported on Linux x64 (see docs). It'd probably make sense to throw a better error when someone tries to use the native-image-musl option on AArch64.

By the way, we do have plans to add support for Linux AArch64 soon, so stay tuned!
