Thumbs up.

We have no current usages of libjsig in our current hermetic Java testing and prototype development work. So I don't have related concerns if don't produce a `libjsig.a` in the `static-libs` for the short term. Let's check with @dougxc and others from GraalVM side to make sure that they are okay with removing `libjsig.a` from the static libs bundle, before making any changes.
