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.

2011-12-29  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR testsuite/51702
	* 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.
	* gcc.dg/pr35442.c: Likewise.
	* gcc.dg/vector-compare-1.c: Likewise.
	* gcc.dg/vector-compare-2.c: Likewise.
	* gcc.dg/torture/pr36891.c: Likewise.
