Yes that's how I do it :) but I do not want to be running -fno-rtti
tests for boost::function on a regular basis. Also consider that
disabling RTTI comes in two flavors, since on MSVC static typeid is
available even when RTTI is disabled.

This ought to be part of all Boost testing, provided that the Boost
community cares about -fno-rtti (I can say this the other way around
too, if we're not testing the no-RTTI configuration of Boost, then we
don't care about that configuration.)
