* gdb.base/ending-run.c (main): Avoid messing with setvbuf; just

call `fflush' after every `printf', so that the output is produced
at predictable points, regardless of whatever buffering does (or
doesn't) take place.
* gdb.base/ending-run.exp: Adjust tests to expect output to appear
at different points.
