This test validates the correct operation of a BuildDir specification
in avoiding reflection: reflection is the case where the build_dir is
located under the corresponding source dir, and trying to use elements
in the build_dir as sources for that same build dir.
Test based on bug #1055521 filed by Gary Oberbrunner.
