I advocate for explicitly stating that SystemC should be disabled for gcc < 5.0 and making this change in the SConscript with a warning. I don't think the SystemC support is widely used right now, and few people are stuck on 4.8, so I doubt it will affect anyone. We can even include a link to the gerrit patch that fixes it in the SCons warning.
