MOM5 compilation time on NCI is now almost 40 minutes on the NCI gadi system. From memory this is 2-3x slower than it used to be recently.

I think it may be due to some of the optimisation reporting in this commit

Regardless this should probably be optional.

Turns out it is the vectorisation option (-axCORE-AVX2) that doubles the compilation time.

Would need to check out the implications on execution time before removing this.
