I'd be interested in how long it takes if you turn on -O for the stage 1
compiler only. The point being that it'll be slower to compile stage 1, but
that compiler is then used to build all the libraries and stage 2, so the
benefit of having an optimised stage 1 might outweigh the time it takes to build it.
