Since the two largest cases are both "cpu_single_env must be TLS"
(ie (a) system emulation built with KVM support and (b) linux-user),
the set of targets which can be non-TLS is really really small,
and I think (1) makes much more sense.

(I'm assuming you don't want to try to support cpu_single_env
being both per-thread and not-per-thread in a single binary
depending on whether the user passes -enable-kvm or not.)
