If QEMU is configured with the dtrace backend, then built, then
reconfigured without, the build fails.
The culprit is the trace-dtrace.h dependency that many files will
have. Due to this dependency, make will attempt to rebuild
trace-dtrace.dtrace. This is the step that fails. Fix by wrapping
the dtrace rules with ifeq/endif.
