docs: Fix __builtin_object_size example [PR121581]

Andrew Pinski · Andrew Pinski · commit 2be801a805c6 · 2025-08-18T12:20:32.000-07:00
This example used to work (with C) in GCC 14 before the
warning for different pointer types without a cast was changed
to an error.
The fix is to make the q variable `int*` rather than the current `char*`.
This also fixes the example for C++ too.

Pushed as obvious after doing a `make html`.
