Details

We should be explicit with certain environment variables that can impact build output. Tor explicitly sets TZ=UTC, LC_ALL=C and umask 0022 [1]. I think we should do the same.

I'm filing this in Build Config initially since this could conceivably be part of mach. Alternatively, these settings could be done inside each build task in taskcluster, or specified by the Docker image, or even by the worker.
