Yes, it seems like getting rid of CLASSIC32 would be okay since it is

I think Segher pretty much answered this.  We definitely need to get
ALTIVEC back soon for 74xx--currently SIGILL's my init when booting.
Since it sounds like you're still tweaking things in Kconfig files,
I'll leave it to you to take care of it.  If not, just let me know.
