CPU_ENABLE_SSE changed to CPU_DISABLE_SSE

Okay, got a bit carried away and submitted before testing build with the
option on and off. New patch also cleans up unused proc and thread stuctures
in linux emulation and gets rid of MIN redeclaration in the kern directory.
Im not sure what you want to do about imported software. Also, should the
unused proc/td structures in linux be removed? They are just commented out
in this patch.
