See previous message about G-exp and DESTDIR.

+               (string-append "HAREPATH="
+                              (assoc-ref %outputs "out")
+                              "/src/hare/stdlib:"
+                              (assoc-ref %outputs "out")

Likewise, (assoc-ref ... "out") -> #$output


+               (string-append "HAREC="
+                              (string-append (assoc-ref %build-inputs
"harec")
+                                             "/bin/harec"))

Likewise about input labels, though in this case search-input-file.
Or (file-append #$(this-package-input "harec") "/bin/harec").

+               (string-append "AS="
+                              (string-append (assoc-ref %build-inputs
"binutils")

IIRC %build-inputs does not exist when cross-compiling, try "guix build
--target=aarch64-linux-gnu hare".  Also, it is ambigious if you meant
inputs or native-inptus here.  You might need %build-target-input or
one of those instead.  They are undocumented though, so maybe better
use this-package-{native,}-input.  Those don't support implicit inputs
though, so you may need to add the gcc manually (maybe look at (guix
build-system gnu) for how).

Is this used for building the hare compiler itself or for building hare
libraries and applications?

Greetings,
Maxime.
