There are of course remote targets that also don't support tracing.  Not all GDBserver
ports support tracing, or we could even be testing against a server other than GDBserver
(qemu, for example).  Technically, native targets could also support tracing.  See e.g., Yao's
push towards using an IPA with the native target.
