i965: Convert the build to using automake.

This does introduce a warning by the automake build system, that the
missing-symbols test build is non-portable.  That's true -- Mac OS X
can't take something built as a loadable module and just link it as a
library.  Of course, we aren't building this on OS X at all, so it
would be nice to be able to suppress it, but I haven't found a way.

Still, the build is going to be much quieter than we have ever had
before, so I think this is a fair tradeoff until we find a way to shut
that warning up.

v2: Put a link in /lib to avoid transition pains for people.
