There is only one ppc64 machine with the `v8test` label

[targos]

https://ci.nodejs.org/label/v8test/

It's https://ci.nodejs.org/computer/test-osuosl-centos7-ppc64_le-1/
Is there a reason for not having https://ci.nodejs.org/computer/test-osuosl-centos7-ppc64_le-2/ too?

[richardlau]

The only reason I can think of is to not block ppc64 behind V8 jobs, but I don't know we run them often enough for that to be a problem. I'd be up for adding the v8test label to the second machine -- we can remove the label again if we start seeing a large backlog. Thoughts @AshCripps @mhdawson?

[AshCripps]

No opposition from me.

[mhdawson]

I think that might be because I'd only manually installed gn, etc. on one of them at one point. Since I think richard has fixed that up no objections from me.

[richardlau]

Added the label to the second machine.

[richardlau]

Reopening as the second machine is failing V8 CI builds. Most likely due to a missing package(s).

[richardlau]

Ran the following to check the packages installed on both machines

$ ssh test-osuosl-centos7-ppc64_le-1 yum list installed > 1.txt
$ ssh test-osuosl-centos7-ppc64_le-2 yum list installed > 2.txt
$ diff -u 1.txt 2.txt

glib2-devel is on -1 but not -2.
