Summary:                    Setting CMAKE_Fortran_MODULE_DIRECTORY breaks build
on IBM XLF Compiler
Description: 
XLF 10.1 looks for modules in the directories passed to the "-I" switch. CMake
correctly sets -qmoddir= to set the module output directory, but fails to
generate the matching -I switch, causing builds using a non-standard module
directory to fail. 

(The build also fails with the GFortran 3.3.3 as shipped with BG/L with
g77: unrecognized option `-Jmodules')

Steps to Reproduce: 
mkdir tmp
git clone https://matthb2@github.com/matthb2/CMake-XL-Fortran-Module-Bug.git
mkdir build-broken
cd build-broken
cmake -DCMAKE_TOOLCHAIN_FILE=/gpfs/gpfs0/home/matthb2/bluegenexlc-mpixlf.cmake
../CMake-XL-Fortran-Module-Bug/
#snipped
make
