I just run make in the $TARGET/libstdc++-v3 directory, but you can
also use 'make target-libstdc++-v3' IIRC.
However, modifying headers *should* trigger a rebuild of anything that
depends on them, and it does rebuild for me.
And if nothing else has changed then rebuilding the whole gcc should
be very fast anyway, because there will be nothing to do.
