;; GetNativeTarget checks S_ISLNK before canonicalizing it like
;; `readlink -f` would do.
;; Canonicalizing is required because Icecat compares the path
;; against its local database to know if there is an extension
;; update. A path that contains the store path will change every
;; time the package is updated.
