That "\r" (carriage return) at the end of the file says your scripts is
probably saved using Windows-style end of line characters, a CR-LF pair.
Under Unix, only the LF is used for end of line, and the CR is treated
as part of the filename.

To correct it (by removing the CRs from the file), run the following

sed -i "s/^M//" LFS-6.5-untar-list

And don't use Windows to edit Unix shell scripts or config files if you
can avoid it. It just ends up causing problems like this. As a hint,
running the 'file' command on any text file will tell you if it's using
CRLF end of line characters.
