When starting Toaster in managed mode, the user must be prompted to set up the localhost build environment.

There should be choices of not using a localhost environment, or
- select a directory (identified by full path) where the layer sources should be checked out
- select a directory where the build activity will take place.

There are no current explicit correspondent of this information, since the source directory is selected by the user when running "git clone" commands, and the build directory is selected by the user when running "source oe-init-build-env" command.
