Systemd bootloader support doesn't require gnu-efi anymore, avoiding the dependency would be good for LLVM users as gnu-efi doesn't build very well with LLVM tooling. https://github.com/systemd/systemd/commit/51bb422198539d5656d1c15953449191d89a54f5
We made that change ages ago...?
Nevermind, gnu-efi isnt a dependency in the ebuilds >=254. I made the bug too quickly. Apologies.
