The option --enable-deterministic-archives that build deterministic archives is supported by binutils since binutils 2.23 [1][2]. See "Static libraries" chapter [3]. https://reproducible-builds.org/docs/archives/ Enable this option for target and host variant. It was added to Yocto Morty (2.2) in 2016 [4].
