There are some TODOs in `definitions.yml` for the  new LTO variant introduced in SERVER-77732. We want to start running LTO but will address these at a later time.

1. In the `compile_test_and_package_serial_lto_no_unittests_TG` task group. The `compile_all_but_not_unittests` task is commented out because it is timing out after 6 hours. There are other tasks in this group that are failing as well that we need to resolve.
2. We bind mount the /tmp directory to a new directory on the host volume to work around disk space limitations. We should evaluate whether we can/should continue to do this or use a different approach.
3. The `.crypt` task is failing on LTO variants.
