The option should not be needed if your toolchain correctly supports
lto (and it is not needed here). Is it possible that you have to add it
because your build is not really an lto build (since something in your
toolchain - like ar - destroys the lto information but thanks to this option,
compilation succeeds)?

In any case: How exactly (without a script) can I reproduce?

Your binaries are not static.
(ldd would show no useful output for a static binary, see below)

> b) lto enabled


> c) hardened
