This is an impossible request. Having a sum of squares be one requires that the numbers be bounded. Having a normal distribution requires that values are unbounded. You can't have both.

If you drop any requirement of having a "normal" distribution, you can do this:
x = randn(n,1);
x = x/sqrt(sum(x.^2));
The sum of the squares of the n elements in x will always be 1.
