The Fortran "stubs" (subroutines) should be in $PETSC_ARCH/src/vec/is/section/interface/ftn-auto/sectionf.c and compiled and linked into the PETSc library.
The same tool that builds the interfaces in $PETSC_ARCH/src/vec/f90-mod/ftn-auto-interfaces/petscpetscsection.h90, also builds the stubs so it is surprising one would exist but not the other.
