There's more about this than just a visual marker: with the old bootstrap,
you could just cut-and-paste the compilation commands from a build log to
rebuild a specific stage2 or stage3 file, possibly with more compiler flags
(like -g3 -save-temps) added to investigate e.g. comparision failures.
This is now much harder to do: you have to move around the prev-gcc or
stage1-gcc directories or manually fix the command lines.
