These first three need a little more thought. They're fine to as proof
of concept work but we need to find better ways to integrate them.

Specifically:

The siteinfo change is a hack and can't be merged as is. We need to find
a way to change the target_arch or target_os in such a way we can signal
to siteinfo to do something different. I also wonder if using i686-linux
is actually correct for x32 in all cases since x32 does support 64 bit
data types.

The udev update needs various other work as people have commented. We
need to resolve the udev differences between meta-oe and oe-core.

runqemu looks like it can be simplified as it looks like just the kernel
name is different? Is x32 using a different machine config at present?
Can we use the qemux86-64 machine directly and just add some tweaks to
it? That would avoid the need to change the qemu scripting?

Cheers,

Richard
