Check into providing Fortran interface as source file, rather than libscrf

[adammoody]

Because C provides a standard ABI, libscr can be compiled once and then linked to an app built with any compiler. However, we must compile libscrf for each Fortran compiler. If we can provide the Fortran interface via a raw source file or include that apps compile in directly, then we may save on the number of SCR builds one has to have.
