At least I don't feel out in the cold all alone...

Oh that's an ugly hack.  So you build a gcc-2.95.3 compiler to build a
glibc which allows you to buld a gcc-3.x bootstrap you can use to
build a full-up glibc, right?  How long does it take to build a full
cross tree?

So far it looks like the two hacks I mentioned get me a tree.  I'm
starting over to see if I can reproduce a tree.

Is there anyway to turn off *ALL* exception handling?
If so then libgcc2 shouldn't need any of the unwind code which is the
root of the cross-build evil.  Of course we'd still have to tweek
gcc/config/rs6000/linux.h to not try to include signal.h...
