Can you say what the differences between these three are?  Which is the
equivalent of the old "cd gcc; make bootstrap"?

They will stop respectively at stage2 (equivalent of old "cd gcc; make bootstrap2"), stage3 (old "cd gcc; make bootstrap"), stagefeedback (equivalent of old "cd gcc; make profiledbootstrap).

Q4) How to compile all the libraries (libjava, ...) using the stage1
    compiler?
A4) Configure with --enable-stage1-languages=all
... and then do what, "make bootstrap"?

"make stage1-bubble all-target".

I think I have now enough info to make The Page That Should Have Been Created A Year Ago.
