The original description for this was:
"""
Since we clean out do_populate_sysroot if do_configure runs, don't
allow do_populate_sysroot_setscene functions if we're going to
run do_configure.
"""
With RSS, we don't need to clean do_populate_sysroot any more. Since
we no longer do that, this function also has no purpose any longer
and can also be removed.
