Make busybox an optional applet
If it's disabled, code shrinks by about 900 bytes:
function old new delta
usr_bin 10 - -10
usr_sbin 11 - -11
install_dir 20 - -20
applet_install_loc 184 - -184
run_applet_and_exit 686 21 -665
------------------------------------------------------------------------------
(add/remove: 0/4 grow/shrink: 0/1 up/down: 0/-890) Total: -890 bytes

909848 493 7336 917677 e00ad busybox_unstripped
but busybox executable by itself does not say anything useful:
$ busybox
busybox: applet not found
