No, that shouldn't matter. In src/cpu/o3/probe/SConscript, you'll see:
if 'O3CPU' in env['CPU_MODELS']:
SimObject('SimpleTrace.py')
Source('simple_trace.cc')
DebugFlag('SimpleTrace')
if env['HAVE_PROTOBUF']:
SimObject('ElasticTrace.py')
Source('elastic_trace.cc')
DebugFlag('ElasticTrace')
If env['HAVE_PROTOBUF'] is false (ie you don't have the protobuf compiler,
etc. installed), then the ElasticTrace simobject won't be part of the build.
