commit e4c8f21e198e739e279b274c17e9246ea9a6d8e5 Author: Bernhard M. Wiedemann <bwiedemann@suse.de> Date: Wed Oct 24 09:50:26 2018 +0200 x86/efi: Do not insert timestamps in efi files in order to make builds reproducible. See https://reproducible-builds.org/ for why this is good. We only add the option, if ld understands it. Signed-off-by: Bernhard M.
