Just a little more info.

The root cause of the problem is that HOST_ARCH is being set to `uname -i`.

On fedora, this produces "i386". On Gentoo, this produces vendor_id from /proc/cpuinfo.

A better fix may be to set HOST_ARCH to i386 explicitly. Since ioemu doesn't build for x86_32 this seems reasonable.

I've confirmed the build for x86_32. I do not have VMX hardware though so that's all I can do.
