Explicitly enable altivec if it's supported. vect_int tests for
powerpc_altivec_ok, but without the explicit option, if altivec is not
enabled by default, we end up expecting vectorization that doesn't
occur.
Regstrapped on ppc64-linux-gnu. Also tested with ppc64-vxworks7r2
(gcc-12). Ok to install?
for gcc/testsuite/ChangeLog
* gcc.dg/signbit-2.c: Add -maltivec if supported.
