Esteban Küber f0b8e13b59 Do not suggest using -Zmacro-backtrace for builtin macros
For macros that are implemented on the compiler, we do *not* mention the `-Zmacro-backtrace` flag. This includes `derive`s and standard macros.

error[E0369]: binary operation `==` cannot be applied to type `Error`
--> $DIR/derives-span-PartialEq-tuple-struct.rs:8:5

LL | #[derive(PartialEq)]
| --------- in this derive macro expansion
LL | struct Struct(
LL | Error
| ^^^^^

note: an implementation of `PartialEq` might be missing for `Error`
--> $DIR/derives-span-PartialEq-tuple-struct.rs:4:1

LL | struct Error;
| ^^^^^^^^^^^^ must implement `PartialEq`
help: consider annotating `Error` with `#[derive(PartialEq)]`

LL + #[derive(PartialEq)]
LL | struct Error;
