commit 3c0f740 broke the x86_64 buildbot

[Roland McGrath]

Now that the x86_64 & i686 bots are in a generally good shape, folks should
remember to look at them after doing commits to check for regressions you
might have introduced.

The x86_64 bot's check step starting failing after:

	2016-03-07  Florian Weimer  <fweimer@redhat.com>

		[BZ #19269]
		* sysdeps/x86_64/Makefile (tst-audit4): Depend on
		tst-audit4-aux.o.
		(tst-audit10): Depend on tst-audit10-aux.o.
		(CFLAGS-tst-audit4-aux.c): Compile with AVX enabled.
		(CFLAGS-tst-audit10-aux.c): Compile with AVX512 enabled.
		* sysdeps/x86_64/tst-audit4.c (do_test): Call tst_audit4_aux
		instead of inline AVX code.
		* sysdeps/x86_64/tst-audit10.c (do_test): Call tst_audit10_aux
		instead of inline AVX512 code.
		* sysdeps/x86_64/tst-audit4-aux.c: New file
		* sysdeps/x86_64/tst-audit10-aux.c: New file

The bot uses gcc 4.8.4.
