[Beowulf] AMD Athlon with Intel Fortran Compiler, which options?

[Joe Landman]

I thought they still had processor check code in there, that checks the 
intel CPU id, and defaults to p3/p4 base w/o SSE.  You can compile it, 
it just might not select that code path (SSE*).   Does this for  Opterons.
