This #ifdef comes in my view from a "template" use of target/xxx/cpu.c (all 
targets seem to start with this #ifdef), but its use is not consistent 
throughout, it's only here.

When KVM is enabled, correct splitting of TCG and KVM will be required, this 
specific #ifdef is not the solution.

Note that this change is already in master.

Ciao,

Claudio
