[PATCH v2 09/20] target/s390x: Fix type conflict of GLib function pointers

[Kohei Tokunaga]

On Emscripten, function pointer casts can result in runtime failures due to
strict function signature checks. This affects the use of g_list_sort and
g_slist_sort, which internally perform function pointer casts that are not
supported by Emscripten. To avoid these issues, g_list_sort_with_data and
g_slist_sort_with_data should be used instead, as they do not rely on
function pointer casting.

V2:
- Updated the commit message to explicitly explain that function pointer
  casts are performed internally by GLib.
