If bumping `.` *doesn't* do it, I'd probably suggest adding something like:

```rust
#[link_section=".stack.GUARD]
#[keep]
static GUARD: UnsafeCell<MaybeUninit<[u8; 1024]>> = UnsafeCell::new(MaybeUninit::uninit());

#[link_section=".stack.MINSTACK]
#[keep]
static MINSTACK: UnsafeCell<MaybeUninit<[u8; 59 * 1024]>> = UnsafeCell::new(MaybeUninit::uninit());
```
