Hi Guix,

Continuing the discussion Ludo’ started over at guix-devel regarding
package size, note that we have

$ guix size emacs-minimal

but 

$ guix graph --path emacs-minimal libgccjit 
guix graph: Fehler: Kein Pfad von „[email-masked]“ nach
„[email-masked]“

and 

$ guix graph --path /gnu/store/wrzjr2g38f23fqg09rrdcn10va5gc5xl-emacs-
minimal-28.2 /gnu/store/lphzb1z0r4kbb453rsvnw7msrxxzp5r7-libgccjit-

guix graph: Fehler: Kein Pfad von
„/gnu/store/wrzjr2g38f23fqg09rrdcn10va5gc5xl-emacs-minimal-28.2“ nach
„/gnu/store/lphzb1z0r4kbb453rsvnw7msrxxzp5r7-libgccjit-10.3.0“

This is rather curious.  How does libgccjit land in emacs-minimal's
closure?
