Set --distinct_host_configuration=false to save CI build times.

- Will only build using target configuration for tool dependencies. There are
  only a few of those, so it doesn't affect much.
- It's also pretty safe because we do a clean build everytime, so we don't
  need this as an optimization for rebuilds.
