We really need to improve our CI so that it's possible to discover these
build failures. Currently it's quite hard to monitor if they get built
unless you just do `guix build foo`.

The last time this came up [0] it was said that maybe it's not really
correct to make these properties of the package, but rather of the CI
jobs. It makes sense but we need a solution, or stop supporting
underpowered architectures like armhf, because most of those machines
can't build this stuff themselves, and it's not good to advertise
support to people who will just be disappointed later.
