udhcpc: kill undocumented -W, it was a no-op.
fix option parsing in the case some CONFIG_x are off.
disable -b on NOMMU, make backgrounding work correctly
(if a bit differently from MMU case). Previously,
it wasn't working at all.
stop using global data for flags in main(), opt
bitfield works as well.
