x86: don't use P6_NOPs if compiling with CONFIG_X86_GENERIC

P6_NOPs are definitely not supported on some VIA CPUs, and possibly
(unverified) on AMD K7s.  It is also the only thing that prevents a
686 kernel from running on Transmeta TM3x00/5x00 (Crusoe) series.

The performance benefit over generic NOPs is very small, so when
building for generic consumption, avoid using them.
