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.)

Consistently use STAGE_DIR as the output directory. (root-filesystem.sh already did, host-tools.sh was using $HOSTTOOLS, cross-compiler.sh was using $CROSS, and system-image.sh was using SYSIMAGE.)

And genext2fs could suffer the same symlink loop problem with RECORD_COMMANDS, so don't symlink. (The point of host-tools.sh is to build what we can from source anyway, linking to anything but the host toolchain defeats the purpose.)
