powerpc: Convert tests to the new support test-driver

  Change the powerpc tests to use <support/test-driver.c>.
Also replace some of pthread calls to its xpthread equivalent.

Tested on ppc64le.

2016-12-15  Wainer dos Santos Moschetta  <wainersm@linux.vnet.ibm.com>

	* sysdeps/powerpc/test-get_hwcap.c: Use <support/test-driver.c>
	instead of test-skeleton.c.
	(do_test): Replaced pthread_create and pthread_join with
	xpthread_create and xpthread_join.
	* sysdeps/powerpc/test-gettimebase.c: Use <support/test-driver.c>
	instead of test-skeleton.c.
	* sysdeps/powerpc/tst-tlsopt-powerpc.c: Likewise.

I don’t think you should omit the FAIL message here. Other than that, LGTM.

Right.  I could add a TEST_VERIFY macro which would allow you to write:

   TEST_VERIFY (xpthread_join (threads[i]) != NULL);

or

   TEST_VERIFY_FAIL (xpthread_join (threads[i]) != NULL);

(in case execution is not expected to continue).

Thanks,
Florian

I think xpthread_check_return() called from xpthread_join()
is already handling it.

Not for the status == NULL case.

It sounds good. I'll wait your patch instead of printing a fail message to stdout.
