I've tried the reverse now, turning on the options you have turned off on top of my defconfig. This version still works for me, booting with a plain 'qemu-system-x86_64 -kernel arch/x86_64/boot/bzImage' and building with my arm64-to-x86 cross compiler. I have turned off most drivers here to get faster builds, but it's enough to get console output.
