Level 3 BLAS (blas3)

The level 3 BLAS SAT consist of 4 FORTRAN files that exercise the
performance and correctness of the single and double precision real,
and single and double precision complex level 3 BLAS. The tuned
BLAS routines are contained in libkmath.a.  

A customized dclock routine is used to reflect the use of Fab 7
boards. A different dclock should be linked if Fab 5 boards are
used.
