(for cross-canadian recipes RECIPE_SYSROOT points to recipe-sysroot ([1]) ). Because of this mismatch, on rebuild, sstate_clean_manifest() will not clean the files in recipe-sysroot, but will try instead to delete the non-existent files in lib32-recipe-sysroot, which will trigger the FileExistsError afterwards.
