By default Octave is build without static libraries, thus all major
Linux distributions do not provide these files by default either.  One
possibility is to compile Octave yourself using

  ./configure --enable-static

Another way is to link the dynamic Octave libraries.  I don't have
OpenCoarrays to test, but maybe this one might work:

  caf <fortran_source_file.f08> -o <executable_name_of_source_file>
  fortranlib.a -L/path/to/liboctave -loctave
