This is more complicated than we need. OSX "libtool" and GNU
"libtool" are really completely different things. We don't
(these days) do anything that we need GNU libtool for, so
there's no need to depend on it or use it optionally -- we should
just use "ar". If we need to special case the "program for creating
static libraries" for OSX that's annoying but we can do that.
