    libgcc: Avoid warnings on __gcc_nested_func_ptr_created [PR113402]

    I'm seeing hundreds of
    In file included from ../../../libgcc/libgcc2.c:56:
    ../../../libgcc/libgcc2.h:32:13: warning: conflicting types for built-in
function â__gcc_nested_func_ptr_createdâ; expected âvoid(void *, void *,
void *)â
    +[-Wbuiltin-declaration-mismatch]
       32 | extern void __gcc_nested_func_ptr_created (void *, void *, void
**);
          |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    warnings.

    Either we need to add like in r14-6218
      #pragma GCC diagnostic ignored "-Wbuiltin-declaration-mismatch"
    (but in that case because of the libgcc2.h prototype (why is it there?)
    it would need to be also with #pragma GCC diagnostic push/pop around),
    or we could go with just following how the builtins are prototyped on the
    compiler side and only cast to void ** when dereferencing (which is in
    a single spot in each TU).
