When you set up Toaster, after the database is created, the toaster script prints the following messages: -- Validation: The layers checkout directory must be set. -- Validation: The build directory must be set. Even when both directories are correctly set. The messages have been reported as "ominous" and, in any case, they should only be shown if the validation fails. It would be good to remove them when the directories are set correctly, in order to reduce noise and confusion.
According to the 2.1 toaster manual, the TOASTER_DIR env variable is set automatically to the current directory, and only needs to be exported to set a build or clone directory somewhere other than the current directory. Also, even after exporting TOASTER_DIR to the cloned poky directory, the messages still appear.

For the time being remove them. [YOCTO #9097] (Bitbake rev: c57f20f9cd7cb4ea4d285291a1e71e5df7152799)
