Interesting. Not sure it's relevant, but the difference in IR is the missing
`(...)` in front of the callee token:

Does this mean something like "unknown actual parameters"?
It also happens with a `static` function, but here we emit the function body
right away (and we know the actual args in IR):

I guess this is not the whole story though. Printf looks like this:
```
define internal void @__stmts__0() #0 {
entry:
%call = call i32 (ptr, ...) @printf(ptr noundef @.str, i32 noundef 2)
ret void
}
declare i32 @printf(ptr noundef, ...) #1
```
