	These already exist for Altivec, but for some reason your testing
harness is not reporting back failure correctly to disable the tests for
PowerPC.  See

.../gcc/testsuite/lib/target-supports.exp

check_effective_target_powerpc_altivec
check_effective_target_powerpc_altivec_ok
check_vmx_hw_available

	i?86 does not seem to have as many checks.
