If GDB says it can't find the struct the function returned, report
those tests as `unsupported'.
* gdb.base/structs.exp (call_struct_func): New function.
(do_function_calls): Use call_struct_func to call the functions
returning structs.
* gdb.base/callfuncs.exp: The stabs generated by GCC don't tell us
whether functions are prototyped or not, so we can't possibly pass
arguments to t_float_values2 properly.
