Find{BLAS,LAPACK}: improve found message on Cray
With Cray compiler wrappers (implicitly tested on OLCF Spock) the BLAS and LAPACK libraries are automatically linked as necessary through the wrapper script and programming environment. With this change, the configure output is: ``` -- Found BLAS: implicitly linked <snip> -- Found LAPACK: implicitly linked ``` rather than ``` -- Found BLAS: 1 <snip> -- Found LAPACK: LAPACK_LIBRARIES-PLACEHOLDER-FOR-EMPTY-LIBRARIES ```
