Previously were checking for the `__CRAYXC` and `__CRAYXE` predefined macros. These macros reflect the platform that the compiler wrapper is running on, i.e. Cray XC and Cray XE machines. They are not defined on other platforms such as Apollo80. Switch to the `__CRAYXT_COMPUTE_LINUX_TARGET` macro. The Cray cc/CC/ftn wrappers always define this macro on the command line. This macro has been in use for many years, and is believed to be a reliable way to detect current and older Cray compiler wrappers. Fixes: #21904
