Set MPI environment variables to the compiler wrappers on Cray (#2762)

Browse Source 
* Set MPI[lang] env var to compiler wrappers on cray

Sets MPICC, MPICXX, MPIFC etc to point to the compiler wrappers on Cray systems.
Some packages look for MPIs via environment variables - e.g adios

* Use spec to check for Cray

* os is no longer used.
