Stefan Hajnoczi b33b890cd0 trace: avoid SystemTap dtrace(1) warnings on empty files ... target/hppa/trace-events only contains disabled events, resulting in a trace-dtrace.dtrace file that says "provider qemu {}". SystemTap's dtrace(1) tool prints a warning when processing this input file. This patch avoids the error by emitting an empty file instead of "provider qemu {}" when there are no enabled trace events.
