No, as I pointed out, it is caused by the fact that you 'select' EFI

replace
select EFI if ARM64
with
depends on EFI || !ARM64
but it would be even better to make ACPI_APEI depend on ACPI, since
the above dependency will be implied then, although I am not sure how
that affects other architectures.
