# Ship the tracked prebuilt EFI payload (SOURCE4) instead of compiling on targets where the
# gnu-efi toolchain layout does not support elilo's build: ppc64le (no x86 EFI toolchain) and
# EL8 (gnu-efi-devel places elf_x86_64_efi.lds under a path elilo's Makefile does not find).
# elilo-x64.efi is a noarch artifact, so the prebuilt is byte-identical to the compiled one.
# Use the tracked prebuilt on ppc (no x86 EFI toolchain) and on EL8 (gnu-efi lds path gap).
# Three SEPARATE %if blocks, each a single simple compare -- NOT one `A || B` expression (the
# older rpm in the EL8/EL9 mock chroot mis-evaluates `||`), and NOT %ifarch (during `rpmbuild -bs`
# the srpm's BuildRequires are frozen against %{_host_cpu}, not the target). Crucially, alma ppc
# chroots report %{_host_cpu}=powerpc64le while rocky reports ppc64le, so BOTH must be matched --
# that mismatch is exactly why elilo pulled in the (ppc-absent) gnu-efi BuildRequires on alma ppc.
