Not sure if it has improved. If it is the only failing bot I tend to ignore it. Maybe we can ask the admin of the build bot.

I just got an mail from them that they think it is the memory going over the top and dialed down the building parallelism. Since D67847 <https://reviews.llvm.org/D67847> changes only `cpp` file, probably there were too many linking jobs at the same time.
