trace: rebuild generated-events.o when configuration changes
Make sure to rebuild generated-events.o when ./configure options change. This prevents linker errors when a stale generated-events.o gets linked with code compiled against fresh headers. For example, try building with ./configure --enable-trace-backend=stderr followed by ./configure --enable-trace-backend=dtrace. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
