Giant redo to put simple-root-filesystem in initmpfs. NO_NATIVE_COMPILER and NO_ROOTDIRS went away, kernel built moved back into system-image.sh, old root-filesystem.sh and root-image.sh are no longer used, I need to fix up several things (chroot-splice.sh, the lfs-bootstrap build is breaking in mpfr, haven't tested this on all targets yet... but the basics are in.
