Compile tst-cleanupx4 test with -fexceptions

tst-cleanupx4 is linked with tst-cleanupx4.o and tst-cleanup4aux.o.
Since tst-cleanupx4.o is compiled from tst-cleanup4.c with -fexceptions,
tst-cleanup4aux.c should also be compiled with -fexceptions.

Tested on x86-64 and i686.

	[BZ #18645]
	* nptl/Makefile (extra-test-objs): Add tst-cleanupx4aux.o.
	(test-extras): Add tst-cleanupx4aux.
	(CFLAGS-tst-cleanupx4aux.c): New.  Set to -fexceptions.
	($(objpfx)tst-cleanupx4): Replace tst-cleanup4aux.o with
	tst-cleanupx4aux.o.
	* nptl/tst-cleanupx4aux.c: New file.
