Are wanting to disable this by default for OpenJDK, requiring anyone who wants it enabled to add a new configure option, or are we only intending to change the configuration for Oracle builds? If the latter, we should just add the option `--disable-cds-archive-coh` to `jib-profiles.js` for the relevant build profiles.

Per our off-line discussion, I went with the latter approach and have changed the `jib-profiles.js`.

I've reverted the changes to jdk-optinos.m4.
