Customer reported problems detecting the Cray compiler on their Apollo80
system. We were checking for the __CRAYXC and __CRAYXE predefined
macros. These macros reflect the platform that the compiler is running
on, i.e. Cray XC and Cray XE machines. Naturally, this didn't work on
Apollo80.
This commit uses the official Cray compiler identification macros which
are defined on every platform:

version >= 9 __cray__ __cray__ _CRAYFTN
