Change the powerpc tests to use <support/test-driver.c>. Also replace some of pthread calls to its xpthread equivalent. Tested on ppc64le. * 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. Use TEST_VERIFY_EXIT macro. Removed unneeded status variable. * sysdeps/powerpc/test-gettimebase.c: Use <support/test-driver.c> instead of test-skeleton.c. * sysdeps/powerpc/tst-tlsopt-powerpc.c: Likewise.
