The fortran wrappers are always built [if configured with a fortran compiler]

'Fortran interface definitions' gives you extra type checking for the
subroutine calls - when using a f90 compiler.

However this code can have rough edges - so its not enabled by
default. You can use it - and report if you encounter issues.

       Declare PETSc objects in Fortran like type(Vec) instead of Vec  current: 0
<<<<<<<

This is experimental - to provide a bit more native f90 coding support
[instead of preprocessing]. And it does not work with --with-fortran-interfaces=1
