This option causes the selected busybox shell to use busybox applets
in preference to executables in the PATH whenever possible. For

qualified executable name, such as '/sbin/ifconfig' will still
execute the /sbin/ifconfig executable on the filesystem. This option

+ is generally used when creating a statically linked version of busybox

Note that when using this option, the shell will attempt to directly
run '/bin/busybox'. If you do not have the busybox binary sitting in
that exact location with that exact name, this option will not work at
all.
