Subject: Fix Intel and MinGW Fortran DLL import libraries

We add Intel and MinGW Fortran linker options to create the import
library portion of a DLL.  This allows other binaries to link to a
Fortran DLL.

We also update the Fortran test to use a .def file to specify exports
since there is no __declspec(dllexport) markup syntax in Fortran.
