Skip git gc on aix and master/built-in

Issue #20346

[AdamBrousseau]

Test run
https://openj9-jenkins.osuosl.org/job/Update-Reference-Repos-Linux-x86/23/

[pshipton]

Should I be concerned about all the repack errors in the test run?

[pshipton]

Also, should we test this on AIX?

[AdamBrousseau]

The test run was on aix.
I reran another one one the failed machines with CLEAN_CACHE first set.

Why did the 24 job fail?

Can you pls explain how this works, wrt running on master. When does it run on master and when doesn't it?

[AdamBrousseau]

24 failed on aix-11. Not sure why. It was during the fetch. Might have been git out of memory.
Rerun on aix-11 here https://openj9-jenkins.osuosl.org/job/Update-Reference-Repos-Linux-x86/25/consoleFull passed.

For master, we will run the cache update but no git gc since it appears that the gc is what is causing jenkins to fall over. Also no git gc on aix since it doesn't seem to work well either.

Build 23 shows a sucessful run on master without a gc

I understand the logic of the change, what I don't understand is when we run on master, or not. Is master just one of the x86 machines we run on when updating x86?

[AdamBrousseau]

Master falls under the SETUP nodes list (worker). We only run the setup nodes (true) on the xlinux job ever since we divided by platform.
