I think if Spain did join the Axis, Gibraltar would fall under the combined pressure of Italy, Spain, and Germany, but that would not likely change the outcome of the war.

As LG said, a early Western front would likely occur, with the Allies invading Spain instead of Italy, maybe even a year earlier.
