Interestingly, that wiki page says, that LTO should produce smaller
binaries, which clearly isn't the case here.
I wonder whether the wiki is incorrect or whether this is a toolchain
issue or if this is specific to systemd
Or maybe this is Debian specific. Would be interested to see numbers
from other distros.

Concerning the build speed: I wonder whether at least disabling LTO on
our CI would make sense. We don't really care for fast/small
executables there.
