Please, do not top post.  It loses context

fortran@gcc is a list for the discussion of the development
of gfortran.  It is not a phython user support forum.  Have 
asked the f2py developers or on a f2py forum for help?

Instead of using f2py, have you considered using gfortran?

Does 'nm crtoffloadtable.o' show the symbol  __offload_func_table?
If yes, then the answer is obvious.
