What build scenario are you seeing that does NOT want the trace events to be present ? If there is any, then I might even call that situation a bug, as we want trace events to be available as a debugging mechanism for everything we build.

I'm aiming for an embedded system or a VM image that only needs qemu-ga, in which qemu is built with --enable-trace-backends=nop. -- Carlos Santos Senior Software Maintenance Engineer Red Hat casantos@redhat.com T: +55-11-3534-6186

How about install: get_option('trace_backends') != 'nop' ?
