This is from personal experience. The same thing happened to me(4
core, 8 HT, 16 GB RAM). The build kept failing during linking stage. I
went and got another 16 GB but by this time the master branch started
consuming no more than 6 GB. The only change was the LTO linking, so I
assumed it was the thinLTO change and didn't investigate further.
Worth a try!
