I'm agree, but I would like to avoid to spent too much time on it while it
already available from Linaro.

I suggest to call the package providing the prebuilt QEMU_EFI.fd "ovmf-bin" and
latter add the "ovmf" package to build it from source (like the rust packaging
does with "rust", "rustc" and "rust-bin").
