Confirmed that this udhcpc fix is functioning fine: many thanks!

I did have some unrelated problems with git though (and confirmed
still present this morning): Changes to init.c have made the exec line
which is called for items in inittab:
       BB_EXECVP(command, cmd);
(where command is a pointer to the whole command, cmd is an array of
pointers to argv). The whole "command" string (including arguments)
rather than cmd[0]+dash (as was previously done) is possibly not what
you want to ultimately feed into execvp().
