Note: the *-toolchain packages are meant for users, not for packagers.
Since this package fails to compile with GCC, I'll replace this with
the following:

    (arguments
     (list #:phases
           #~(modify-phases %standard-phases
               ;; Use Clang instead of GCC.
               (add-before 'configure 'prepare-build-environment
                 (lambda _
                   (setenv "AR" "llvm-ar")
                   (setenv "NM" "llvm-nm")
                   (setenv "CC" "clang")
                   (setenv "CXX" "clang++"))))))
    (native-inputs (list clang llvm))
