Hm...  Oh!  I didn't notice this bit:

Test package-test-macro-compilation-gz condition:
    (file-notify-error "hashing failed" "/home/larsi/src/emacs/trunk/test/lisp/emacs-lisp/package-resources/macro-builtin-package-1.0/macro-builtin.el.gz")

So it passes this test:

static Lisp_Object
comp_hash_source_file (Lisp_Object filename)

[...]

#ifndef HAVE_ZLIB
  if (is_gz)
    xsignal2 (Qfile_notify_error,
	      build_string ("Cannot natively compile compressed *.el files without zlib support"),
	      filename);

But then signals an error here:

#ifdef HAVE_ZLIB
  int res = is_gz
    ? md5_gz_stream (f, SSDATA (digest))
    : md5_stream (f, SSDATA (digest));
#else
  int res = md5_stream (f, SSDATA (digest));
#endif
  fclose (f);

  if (res)
    xsignal2 (Qfile_notify_error, build_string ("hashing failed"), filename);
