    toaster: tests Automated build-mode backend tests
    
    Add tests to check various backend scenarios that
    require UI interaction.
    
    Add necessary files for above tests (the sqlite file
    and the default config json).

introduces a dangling symlink:

lib/toaster/contrib/tts/toasteruitest/toasterconf.json -> ../../../../../../meta-yocto/conf/toasterconf.json

meta-yocto only exists at that place in Poky, but not in other distros using bitbake.

With the dangling symlink in place, do_populate_sdk_ext fails:
