CRAY-version:
- change FC to cf77
- change LD to cf77
- change FFLAGS (if you want to use dgemm.f): -Zv -Wf,-dp
- add to CFLAGS -DXDGEMM=SGEMM

Cray will pick up automagically SGEMM.o from SCILIB.

ONYX-version:
- Compile Fortran with -O2 -sopt,-r=3 -mips2 if you want to speedup the dgemm.f
- Use BLAS dgemm.o: Link with -L/usr/lib -lblas  and dgemm.o will come automat.


With CRAY: Get rid of NCPUS env parameter.
