- use openwrt locations for utilities, fixes compilation on systems missing those utilites, allows ipkungfu to run
- $(INSTALL_BIN) to properly install binaries
- rewrite to use insmod in place of modprobe
- depends on bash
- delete autogenerated md5sum manifsts during removal, fixes reinstallation/upgrades
- needs more work, but this is a start and prevents error during compilation
