I don't think so.  I'm pretty sure that RTTI support requires some
architecture+OS specific help which we don't provide.  We have certainly
used -fno-rtti in the kernel since Day 1, so I doubt that you'll have
much luck with it.

n.b. I'm not a C++ guru, so may answer may be inaccurate (as well as 
biased against such things)
