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.

libbb is BusyBox's utility library. All of this stuff used to be stuffed into
a single file named utility.c. When I split utility.c to create libbb, some of
the very oldest stuff ended up without their original copyright and licensing
information (which is now lost in the mists of time). If you see something
that you wrote that is mis-attributed, do let me know so we can fix that up.
