Git memory failures on ubuntu1404-32

[tniessen]

I saw a couple of weird Git failures on ubuntu1404-32 recently:

From https://ci.nodejs.org/job/node-test-commit-linux/21641/nodes=ubuntu1404-32/console:

This seems to be the same issue as nodejs/node#22628 – python has been seeing memory errors there too, which sounds like something with the OS or the hardware is broken.

Even more failures:

make had a segmentation fault... And also this.

[refack]

We actually shouldn't be testing node >= v10 on 32bit platforms. I'm waiting for reviews on #1498 to solve that.

[refack]

Ok. #1498 landed, and I marked https://ci.nodejs.org/computer/test-softlayer-ubuntu1404-x86-1/ as offline.
