By this we mean that the fortran release that goes with XL C/C++ 11.1 is 13.1.
Having such a difference in version number is confusing spack quite a lot.
Most notably if you keep the versions as is the default xl compiler will only
have fortran and no C/C++.
So we associate the Fortran compiler with the version associated to the C/C++
compiler.
One last stumble. Version numbers over 10 have at least a .1 those under 10
a .0. There is no xlf 9.x or under currently available. BG/P and BG/L can
such a compiler mix and possibly older version of AIX and linux on power.
