arch/i386/Kconfig.cpu considered harmful
Do we really need to pull that into the UML Kconfig? We need some of the things it defines, like X86_CMPXCHG, but people keep discovering that menu and trying to set it to match the host, causing compilation problems when that pulls in headers that UML doesn't have.
I think I would like to dump Kconfig.cpu and define for ourselves the symbols that we need.

Yes, I didn't fix these problems. I've been fairly lazy, I must admit this.

How do you let the user choose the CPU he wants to optimize for? That was the first purpose of what I did - optimizing for 386 isn't exactly the best thing to do (and we've done this, till the menu was introduced).
We can restrict the choices in the menu, for now, with a dependency on ! UML for the ones which don't work (i.e. the ones using 3DNow in string operations, IIRC). M686, Athlon and likely Pentium 4 work at least.
