Wait my proposal cannot work as-is because linux-architecture=#false
for Hurd platforms ...

FWIW, I think the current usual behaviour is not ideal, and that these
kind of procedures should raise an exception instead, like
specification->package:

scheme@(guix-user)> (specification->package "foobar")
guix repl: fout: foobar: onbekend pakket ; <-- unknown package

Or search-input-file or search-input-directory.

Maybe it could raise a &non-linux-platform condition like
search-input-file raises &search-error condition?
