OK, if this works after the build is complete, then you are going to
need to stop the build in the middle.  Fortunately, this can be done
easily enough by running "make configure-stage2-gcc".  That should stop
after the stage2-gcc directory is configured.  At that point, you should
see a stage2-gcc directory and a prev-gcc directory.  Presumably the
stage2-gcc/config.log file will show a failure, and with luck you will
be able to recreate that failure at that point.
