Fix cmake build.

This is an attempt to fix the cmake build. For some reason, it has recently started failing with a permission denied trying to overwrite `/tmp/build.log`.  This file exists from the `build-toolchains.sh` step, which is owned by the rustbuild user. I think there is some behavior where a sticky `/tmp` directory doesn't allow overwriting files owned by other users even when running as root.  I do not know why this has suddenly started, and I can't reproduce locally with my own docker setup. However, this fix seems to work on CI.
