[RFA] v3 tweak for overload.exp

[Michael Snyder <msnyder at cygnus dot com>]

This test wants to use a command of the form:
	list foo(void)
to test the handling of overloaded function names.

This change allows the test script to choose between
	list foo(void)
and 
	list foo()
depending on whether we're using the v3 model or the old one
(well, really depending on which of the two works).
2001-10-31  Michael Snyder  <msnyder@redhat.com>

	* gdb.c++/overload.exp: Select overloadfnarg(void) or overloadfnarg(),
	depending on what the symbol table contains.
