These are both cases of overly aggressive error messages. build_aways was
deprecated in 0.47 which is newer than 0.45 (which is our current oldest
supported version of meson). There is an issue filed against meson about not
printing the deprecated message in these cases, it looks like there's just a
couple of issues to iron out:
