Updates:

- Qt 5.15 has been built on the factory
- Slicer build failed with `malformed mach-o: load commands size` error.
  - A first attempt to address the problem was implemented in [Slicer/DashboardScripts@26a343](https://github.com/Slicer/DashboardScripts/commit/26a343d5670b97aac7b7d004f95041c6f6692231) by changing the basename from `Slicer` to `S`.
  - With that change to number of failed tests went from `77` to `44`

Next steps:

- Update to use `P` instead of `Preview` and `S` instead of `Stable` to address remaining failures.
