The lines were added as part of the original Fortran support:

As Michael pointed out this probably has to do with Fortran 90 .mod
files.  The Intel compiler loads them from the include files search
path.  Contents of .mod files may be configuration-specific so perhaps
the compiler puts them in the per-config output directories.

I was not personally involved in adding those particular lines though.
