Currently, the build scripts enable AltiVec unconditionally on all ppc*
targets. However, there some ppc* targets which do not support AltiVec
instruction set extensions, these are often embedded systems like the
PowerPC e500 or similar which have their own type of instruction set
extensions like SPE. Trying to enable Altivec support on these targets
results in a compiler error, hence we need to add an autoconf test for
AltiVec support before trying to enable it on ppc* targets.
