Cool.

AFAICS, this causes a rebuild of the cross-compilation infrastructure
only (for Hydra, that’s several times GCC plus a bunch of packages that
we cross-build to make sure the basic functionality is alright.)

So it could even go to ‘master’, but since Hydra is now building all of
‘core-updates’, it’s more energy-efficient to push it to ‘core-updates’
as well.

LGTM!
