Change the default compilation flags for the Intel Fortran compiler.

Change the default compilation flags for the Intel Fortran compiler.

The LAPACK TESTING should run error free with these settings.

Previously were:
	OPTS     = -O3
	NOOPT    = -O3 -fltconsistency -fp_port
Now are:
	OPTS     = -O3 -fp-model strict
	NOOPT    = -O0 -fp-model strict

Thanks to Viswanathan Elumalai the University of Pittsburgh for reporting the
problem, Jason Riedy for suggesting to use the flags "fp-model strict" and Osni
Marques for playing with a lots of flag combinations!
