Subject: [PATCH] autoconf213: move 'm4' and 'perl' to nativeBuildInputs
 (strictDeps = true)

Without the change `strictDeps = true` build fails as:

    $ nix build --impure --expr 'with import ./. {}; autoconf213.overrideAttrs (oa: { strictDeps = true;})'
    Error: Autoconf requires GNU m4 1.1 or later
