Actually I'm not sure I understand where the limits comes from; it seems
when using 32 bits there's a 2 GB limit somewhere:

Note that you'll want to use the latest commit available of mrustc, or
something recent enough like this in (gnu packages rust) as it includes
recent fixes to the (still failing) i686 build:

;;; Note: mrustc's only purpose is to be able to bootstap Rust; it's designed
;;; to be used in source form.  The latest support for bootstrapping from
;;; 1.39.0 is not yet released so use the latest commit (see:
(define %mrustc-commit "c7066542f8e93d320323749216bf3c82aecb67c2")
(define %mrustc-source
  (let* ((version "0.9")
         (commit %mrustc-commit)
         (revision "1")
         (name "mrustc"))
      (method git-fetch)
      (uri (git-reference
            (url "";)
            (commit commit)))
      (file-name (git-file-name name (git-version version revision commit)))
