I noticed that dg.gcc/torture/vector-1.c and dg.gcc/torture/vector-2.c were
failing on 32-bit PowerPC Linux systems. The failure was due to the compiler
complaining that by default the ABI on 32-bit does not allow passing vector
items. I fixed the tests so that they pass -mabi=altivec on powerpc systems.
I ran the dg-torture.exp tests, and these two tests now do not fail on 32-bit
PowerPC. Is this ok to install in 4.7?

* gcc.dg/torture/vector-1.c: On powerpc add -fabi=altivec to avoid
failure on 32-bit systems.
* gcc.dg/torture/vector-2.c: Ditto.
