The configure.in fragment for v2 starts off by seeing if cc1plus exists.
If it does, v2 is built; if it doesn't, v2 flags configure to skip itself.

The stuff for v3 doesn't have anything like that.  You could probably get
by with --disable-libstdcxx-v3 (or however it's spelt) to revert to v2,
which would then disable itself.  I will be working this weekend on a more
general "do X if Y is built" method; DJ Delorie and I have been tossing
messages back and forth on gcc-patches about an approach.
