Intel's f90/95 compiler wants to be called ifort now instead of ifc

[Tom Epperly]

The Intel F90/F95 compiler version 8.0.34 (and higher presumably) prints 
a warning message if invoked via the name ifc telling you that it should 
be invoked via the name ifort.

bash-2.05b$ ifc -V
ifc: warning: The Intel Fortran driver is now named ifort.  You can 
suppress this message with '-quiet'
Intel(R) Fortran Compiler for 32-bit applications, Version 8.0   Build 
20031016Z Package ID: l_fc_p_8.0.034
Copyright (C) 1985-2003 Intel Corporation.  All rights reserved.
FOR NON-COMMERCIAL USE ONLY

ifort: Command line error: no files specified; for help type "ifort -help"
bash-2.05b$

It would be nice if autoconf checked ifort before checking ifc, so ifort 
would be used when available.
