Ok, this commit is _huge_ and its gonna change the world. I've

been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied.  Well, I'm finally am
happy with the new config system, so here it is.  This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
    http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.

I have thus far updated only x86.  I'll be updating the other
architectures shortly.
