This test verifies:
    1)  that we don't build files when we use the -n, --no-exec,
        --just-print, --dry-run, and --recon options;
    2)  that we don't remove built files when -n is used in
        conjunction with -c;
    3)  that files installed by the Install() method don't get
        installed when -n is used;
    4)  that source files don't get duplicated in a BuildDir
        when -n is used.
    5)  that Configure calls don't build any files. If a file
        needs to be build (i.e. is not up-to-date), a ConfigureError
        is raised.
