Those *provide* older Mesa version, so naturally people want to build
latest Mesa on them (especially if they've just bought HW that isn't
supported by distro version of Mesa).  Building would fail if Mesa would
require newer Meson version than the one in the distro.

PS. On Ubuntu 18.04 LTS, one can install 0.47 Meson binary package
from 18.10, it works fine.  Maybe something similar can be done also
on other LTS distros.
