Build static native image for linux amd64 system

[gzm55]

Static native image improves the portability between different libc types (glibc or musl) and glibc versions on x64 linux.

Sounds good.
This will need to be integrated into https://github.com/apache/maven-mvnd/blob/master/.github/workflows/release.yaml
Not sure about the cost of building musl during the GitHub release workflow though...

[gzm55]

from graalvm ga example, it is already integrated with option native-image-musl

Indeed, this would be nice!

@gzm55 do you happen to know how much bigger will the native executable become?

not yet, i will try it at weekend

the preparation of the tool chains takes less than 1 minutes, and the increasement of the image sizes can be ignored, less than 1%.

The problem is that the embedded JNIs still depends on glibc:
