Some of those changes for icc don't make sense. Setting "CC" to "icc
-i-dynamic" looks for an executable file name of the entire string...
causing:
Configuring MVAPICH2...
Configuring MPICH2 version MVAPICH2-0.9.8 with
--prefix=/var/tmp/OFED/usr/ofed/1.2.5/mpi/intel/mvapich2-0.9.8-15

checking for C compiler default output file name... configure: error:
C compiler cannot create executables
See `config.log' for more details.

Is there a good way to fix this?
