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.
