Depends on what you mean by necessary.

Without it any output to stdout generated by the shell command will be
inserted into your makefile, which will almost certainly become a syntax
error.

As long as you're confident that the script you run will never generate
any output on stdout (or you are happy to receive a syntax error if it
does), then no, the assignment is not necessary :).
