I don't know if this is really a bug, or is all OK, but I think it should at least be checked.
I've seen in [1], that in order to have lto working, you needs libelf-0.8.12, but instead, it has a dep on >=dev-libs/elfutils-0.143.
Is is ok?

Reproducible: Always

Yup, it's an alternative for libelf. You can look at gcc's config.log to see it's happy with elfutils :)
