Yes, the general principle is: the tool identifies itself with the name
under which it was invoked.  Compare (on GNU system):

  $ mv foobar x
  mv: cannot stat `foobar': No such file or directory
  $ /usr/bin/mv foobar x
  /usr/bin/mv: cannot stat `foobar': No such file or directory

Aha, yes, I see.  Currently there is no easy way to achieve this, but it
should not be hard to implement. Right from the top of my head I'd
propose an option telling cflow to display only those symbols
that are defined anywhere in the sources it is given in the command
line. Will such an option help?
