This setting will cause r-a to invoke the build script command only once in the root of the project instead of once per workspace which causes problems when the `linkedProjects` settings is used to target other workspaces in the repo.

In theory the same setting could be applied to `checkOnSave`, but for that to work `x.py` needs to fix up the paths of diagnostics to be relative to the project root instead of the workspace roots the diagnostics are emitted from.
