???  You're putting the output in a .s file?  .s files are for assembly
_source_, not object code.

exit.s ABSOLUTELY MUST EXIT before running the above command.

exit.s should contain the code as listed in the book.
After you have exit.s, you do
as exit.s -o exit.o
exit.o now has the object code. Now you do
ld exit.o -o exit
exit is now the full executable and can be run like this:
./exit

Do an ls -l of the directory you are working in and send it to the list.
