Discussions on IRC in -releng demonstrate that this change resulted in
the CXXFLAGS variable *disappearing* from the stage3 make.conf. I
consider this a regressoin. I haven't personally looked as to how this
happened (although I'm familiar with the code from ARM profile changes),
but I think that also needs fixing. All my workstations descend from the
time when both CFLAGS *and* CXXFLAGS were set in make.conf and I hadn't
noticed this until today; however, this is a secondary issue to the one
that Ben has highlighted, which is a rather unhelpful fall-back
situation for x86 users ..MJE
