gcc.c-torture/execute/vector-compare-2.c was FAILing on Solaris 8 and
9/x86 with ABI warnings
output is:

FAIL: gcc.c-torture/execute/vector-compare-2.c compilation, -O2 -flto
-flto-partition=none
but strangely only with -flto, although the message also appears
without. Closer investigation revealed a mess:
* If I just run this single test with runtest, it fails for all options,
not just -flto.
* The notes are pruned by gcc-dg-prune, but that isn't normally loaded
by execute.exp. If you do load it explicitly, the notes are pruned as
during a regular testsuite run. I suspect that some other driver is
loaded together with execute.exp which causes this.
* The -flto tests still fail because of a single message that isn't
pruned:
In file included from :0:0:
Only lto.exp (not loaded here) does prune that one.
To avoid that mess, I've simply added a .x file which adds -Wno-psabi.
Tested with the appropriate runtest invocation on i386-pc-solaris2.8 and
i386-pc-solaris2.11, installed on mainline.
