The previous patch made 64-bit booke KVM build again, but Altivec
support is still not complete, and we can't prevent the guest from
turning on Altivec (which can corrupt host state until state
save/restore is implemented).  Disable e6500 on KVM until this is
fixed.

Mihai has posted RFC patches for proper Altivec support, so disabling
e6500 should only need to be for 3.10.
