bumblebee unit test appears to fail using IFORT

[Philipp137]

Unit test fails with 3 sad tests, when using following compiler options on cluster 12:

source /opt/intel/composer_xe_2011_sp1.11.339/bin/ifortvars.sh intel64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/mvapich2/1.8a2/intel/lib64
export FPATH=/opt/mvapich2/1.8a2/intel/include
export PATH=/opt/mvapich2/1.8a2/intel/bin:$PATH

The sad tests which fail differ in the number of blocks with the reference files!
