Inside the Buildkite sandbox, the /tmp directory lives on a tempfs that is backed by 1GB of RAM.

On certain Buildkite jobs (e.g. when we run the Pkg test suite with the Pkg server disabled), we end up cloning a lot of Git repos, and as a result we end up running out of space in the tempfs.

While /tmp lives in the tempfs, the build directory (the current working directory to which the Julia repo has been cloned) is actually backed by a real filesystem. So we want to tell all programs to create temp files and temp directories inside our current working directory.

Increase the size of the tempfs?

We could do that. I know that @staticfloat and @maleadt have expressed concerns about that in the past. We have multiple Buildkite agents on each machine, and we don't want to use up too much RAM.
