What about -march ?  At one point that was something that you weren't
supposed to change unless using stage1.  If one changes -march after
stage3, are we supposed to first run bootstrap.sh before emerge -e ?

Although I always did stage1 installs, I must confess to once getting
into trouble by changing USE flags "too early".  This taught me the
advantage of first going stage1-->stage2-->stage3 with the std USE
flags and only then changing USE flags.  I realize that in that case
one might as well start with stage3 (assuming you can change -march).
