Maybe. The first step would be to install the stage 1 compiler
to a temporary area rather than to the final destination,
I think. (You'd need to install binutils twice, too.)

That's a GCC feature, or lack thereof. I haven't experimented
with it. I think it's supposed to work with recent gcc's,
but I'm not sure. Montavista supports that, and they had
to have a patch for the gcc-3.0-era stuff; I don't know if
that patch was ever integrated.

If this is something you want, go ahead and see if you
can get it to work. I already mentioned the first step;
maybe there isn't much more to it. We won't know until
