Fully static native images on linux/arm64 support

[axelfontaine]

As described in graalvm/container#70 the blocker for being able to create fully static native images on linux/arm64 is GraalVM only supporting muslib on AMD64.

Hi, Thank you for your suggestion, we'll take a look at it shortly.

@oubidar-Abderrahim do you have some ideas what concrete technical blockers are here?

That is, we are blocked because "GraalVM only supporting muslib on AMD64", so the next question is why GraalVM cannot support muslib on ARM64?

This blocks development on current Apple hardware.
