Lots of comment updates. Add a NO_HOST_TOOLS=1 config option, and a few "time" calls to stages that didn't have them. Put native-compiler.sh after root-filesystem.sh in build so it's slightly easier to document.

Since gene2fs can't produce large images in a reasonable amount of time, make a 64 meg image and resize it if necessary. (This means the minimum image size is 64 megs, because gene2fs won't run unless you specify a size, but it knows right away if the size you gave it wasn't big enough. I don't understand this either.)
