Use a recent OMR acceptance build as bootjdk for AIX and for s390x Linux

[keithc-ca]

No builds are available from Adoptium for these platforms.

There were some outstanding problems on zlinux, it would be good to wait for the next nightly.

outstanding problems on zlinux

Would those problems inhibit its use as the boot jdk?

[pshipton]

Perhaps. If you don't want to wait for tonight, run a build now.

[keithc-ca]

We can wait: It would require manual intervention to remove problematic boot JDKs cached on each build machine.

[pshipton]

There is also #17337 which doesn't have a fix yet. It seems to only affect jdk8, but who knows. When ready, I will try this in a PR build first so if there is a problem we only have one machine of each flavor to fix.

URLs for AIX and Z Linux were reversed - now corrected.
Z Linux updated to a more recent OMR acceptance build.

jenkins compile zlinux jdknext

Z Linux build: https://openj9-jenkins.osuosl.org/job/PullRequest-OpenJ9/3773/

[keithc-ca]

URL for AIX updated.

jenkins compile aix jdknext

[pshipton]

jenkins compile aix,zlinux jdknext depends ibmruntimes/openj9-openjdk-jdk#openj9-staging

[pshipton]

The first AIX build is https://openj9-jenkins.osuosl.org/job/PullRequest-OpenJ9/3774/

[pshipton]

The head stream builds work, and the staging builds appear to be working, I'll go ahead with the merge.
