PATCH: Don't dump core in posix/transbug

[H. J. Lu]

posix/transbug failed for me with gcc 3.3. It may be a compiler bug.
But it shouldn't dump core. Here is a patch.

BTW, Changelog entry says

	* posux/transbug.c: New file.
	     ^

	* posix/transbug.c (run_test): Return 1 for failure.
	(do_test): Compare only if run_test is successful.
