[PATCH][BZ #16149] Fix tst-cleanup2 & tst-cleanupx2 failures.

[Ondřej Bílka]

>From bugzilla

Since gcc r204414 tst-cleanup2 & tst-cleanupx2 fail:

Attempting to sprintf to null ptr
Didn't expect signal from child: got `Illegal instruction'

As this test already catches SIGSEGV it suffices to add SIGILL handler.

OK to commit?

	* nptl/tst-cleanup2.c (do_test): Add SIGILL handler.
