I am somewhat surprised we even have `static-libs-bundles` as additional target in what I would consider a generic build-linux job! It looks cleaner to yank `static-libs-bundles` into a separate build job.

Please do not remove the static-lib-bundles - they are critical for testing OpenJDK PRs against libgraal: https://github.com/dougxc/openjdk-pr-canary/blob/9c38cdb2dcdbe4aef6b81732b3a296856ac1bb4c/.github/scripts/test-openjdk-pullrequests.py#L818
