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.

I think this is good. The static libs situation is somewhat messy due to historical reasons, and it is not always easy to know what is the best improvement, in the short term or in the long term.

I would like to remove the old `static-libs` target and replace it with the new `static-jdk-image`, but we're not there yet. In the meantime, I think it makes sense to separate it out cleanly as you have done here.
