EFI stub support is only missing for a 64 bit kernel on 32-bit firmware,
on 64-bit kernels, EFI stub works as usual.

Matt, I don't know if this help was intentionally discouraging,
however, out of curiosity, I tested this with ovmf, and the
kernel boots fine on 64-bit firmware bit with EFI stub, and on
32-bit firmware using efilinux.
Documenting this properly is important for distribution kernels.
We would want to support this on Arch, but not if it means
introducing a regression for EFI stub users.
