In 1.26.2, it does:

$ busybox | grep 'BusyBox v'
BusyBox v1.26.2 (2017-01-16 16:47:56 CET) multi-call binary.

$ busybox udhcpc --help
BusyBox v1.26.2 (2017-01-16 16:47:56 CET) multi-call binary.

Usage: udhcpc [-fbqRB] [-a[MSEC]] [-t N] [-T SEC] [-A SEC/-n]
        [-i IFACE] [-P PORT] [-s PROG] [-p PIDFILE]
        [-oC] [-r IP] [-V VENDOR] [-F NAME] [-x OPT:VAL]... [-O OPT]...

        -i,--interface IFACE    Interface to use (default eth0)
...
        -C,--clientid-none      Don't send MAC as client identifier
Signals:
        USR1    Renew lease
        USR2    Release lease
