Bug#593485: liboil: please make it built on powerpcspe

Package: liboil

On powerpcspe it fails to build because it always tries to use AltiVec,
even if it is not available. I attached two patches which compile and
use AltiVec only if AltiVec is available. I haven't build tested it on
powerpc with AltiVec due to lack of hardware atm. It should work :)
I also redid autofiles where I changed them.
