Well a mistake in the configure script is making it set for everything.

After fixing that there is the problem of how to build merge.c in
deinterlace with only -maltivec for the altivec merge function, and not
the rest of the file which is supposed to be the generic C implementation.

I guess like the yuv file that has altivec support, the altivec merge
function needs to be built by itself with -maltivec while the rest of
the file is built without it.

I am trying to figure out how to do that but haven't quite figured it
out yet.  Certainly that is the correct way to fix it.
