v1: 20250128004254.33442-1-richard.hender...@linaro.org For v2, immediately disable 64-on-32 TCG.
I *suspect* that we should disable 64-on-32 for *all* accelerators. The idea that an i686 binary on an x86_64 host may be used to spawn an x86_64 guest via kvm is silly and a bit more than niche. Similarly for mips32 spawning mips64 and ppc32 spawning ppc64. But in the meantime, jump through a couple of hoops to keep these kvm and xen cases building, while disabling tcg in the same binaries.
