LTO is not enabled for i386: "Compiler flags for LTO are injected in dpkg-buildflags, and can be overridden in the package build. LTO will be enabled on amd64, arm64, ppc64el and s390x. " I don't even know if lto can be enabled on 32bit architectures.

LTO are linker flags, so it's correct to have them exposed in LDFLAGS.

Foundations take care of build flags and i386, I'm subscribing their team.
