This test is now failing on powerpc64-unknown-linux-gnu due to warning messages
being emitted for 32-bit.

FAIL: c-c++-common/torture/vector-compare-2.c  -O0  (test for excess errors)
FAIL: c-c++-common/torture/vector-compare-2.c  -O1  (test for excess errors)
...

This is due to the fact that in the old location the compile command included
-w which suppressed warnings, whereas the new location does not. The test can
be fixed for powerpc by adding the following line (as is present in
c-c++-common/vector-compare-2.c).

/* { dg-options "-mabi=altivec" { target { { powerpc*-*-linux* } && ilp32 } } }
*/

But it looks like this same test started failing on i686-pc-linux-gnu
(http://gcc.gnu.org/ml/gcc-testresults/2012-09/msg01842.html), guessing for the
same reason. Not sure if there's some similar type option that can be added for
that target or whether '-w' should just be added to the testcase.
