Several of the gcc.dg tests were failing on 32-bit powerpc-linux since the
tests test the machine independent vector support, and the powerpc backend
issues a warning on passing vectors if -mabi=altivec was not used (it is on by
default for 64-bit). I committed the following patch as obvious to add the
-mabi=altivec option in this case.

* gcc.dg/scal-to-vec1.c: If 32-bit powerpc-linux, add the
-mabi=altivec option, which suppresses a warning message about
passing vectors by reference. The extra warning causes some tests
to fail.
* gcc.dg/scal-to-vec2.c: Likewise.
* gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c: Likewise.
