We cannot have TCG code in powerpc_excp because the function is called

Fortunately, the Alignment interrupt is not among the ones dispatched
from kvm-only code, so we can keep it out of the disable-tcg build for
now.

Perhaps we could make powerpc_excp TCG only and have a separate
function that only knows the two interrupts that we use with KVM
(Program, Machine check). But for now this fix will do, I think.

Shouldn't we move that code under ppc_cpu_do_unaligned_access ?
