build.log.xz (slightly past warning)
Noticed when bootstrapping GCC 13 from trunk at r13-4681-g531ca06c007d4c.
```
/var/tmp/portage/sys-devel/gcc-13.0./work/gcc-13.0./gcc/rust/rust-lang.cc:67:17:
warning: type [-Wodr]

```
I've attached the build.log compressed a bit past the point of the warning, as
it's still building.
Host compiler is 12.2.1_p20221210.
