Electron 4.0.x does not run on 32bit Linux

[bpasero]

So far I have not been able to produce a green Electron 4.0.x build on Linux 32bit. It always seems to be stuck in tests, e.g. from https://monacotools.visualstudio.com/Monaco/_build/results?buildId=43452

I believe this is due to electron/electron#16407

[bpasero]

Closing as designed, with Electron 4 we will no longer support Linux 32bits. See https://electronjs.org/blog/linux-32bit-support

I need to pull a bunch of stuff out of the build for this still.

Fixed in 7b0cd32 (#73119)
