commit: https://git.buildroot.net/buildroot/commit/?id=f3bacda0c0e0adb2ac7f515476f6bb83d1385130
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As explained in [0], meson recognises a certain set of CPU famillies,
whose names slightly differ from those we know them as.

If we don't pass the proper cpu_familly, meson whines:
    WARNING: Unknown CPU family 'i686', please report this at [...]

Subsequently, packages that use that to decide on what they should build
and how they should build it, fail to build. That is the case for the
upcoming systemd-boot, for example.

Fix that by using the list propvided by the meson documentation [0].
