[Clfs-support] i586 target with cmov

[Chris Fowler]

I've just finished chapter 6 of Sysvinit 3.0.0.  My goal is to target an
i586 processor that lacks features of i686. such as cmov.

I think I may have made a mistake during the initial builds.

Maybe I have not, I just want to validate before I move on.  Host is
 Ubuntu 15.10 x86_64.
Target is a RDC3308 RISC, but it prefers to be x86.
