Fix installation of .mod files. CMake runs Makefiles from the top level
build directory and so the .mod files end up there rather than in
bindings/f95. This is a little ugly. I notice that ifort and pgf90
have a -module <dir> command option to control where these files are
put. Is this option widely available? If so, I suggest we use it.
