I broke gdb.ada/start.exp, and did not notice it, because it outputs an UNTESTED if gdb_start_cmd fails. I don't really see when start would fail and it's not a problem that should be looked at. Change all spots that call untested after a gdb_start_cmd failure, use fail instead. Doing so caused some failures with the native-gdbserver board. Some tests that use "start" were relying on the fact that start would fail with that board to just return with "untested". Change them to add an early return if use_gdb_stub returns true. Some gdb.pascal tests also failed with native-gdbserver, because they did use gdb_start_cmd to start the inferior, for no good reason. Convert them to use runto_main instead, which does the right thing if the target is a stub. A further refactoring could be to make gdb_start_cmd match the expected breakpoint hit and the prompt, which it doesn't do currently (it leaves that to the callers, but not all of them do).
