There are not so many cases where we build host-libxml2 in fact. There
are some, but not that many.

Right.

Well, with --with-included-libxml, the build is reproducible, since the
internal libxml library is always used. But I agree that our policy is
generally to use the non-bundled versions of the different libraries.

It's just super annoying to have yet another dependency, for this silly
--color option of gettext that nobody cares about...
