I dont think there was ever any global option to enable/disable long
options, there are a half-dozen applets that have a menu item to
enable/disable long options for that specific applet.

There may have been talk about a global option, im not aware of it being
implemented.

The bb_applet_long_options variable is used by an applet to make
bb_getopt_ulflags aware that the applet wants to use long options.

Actually, long options are one of the reasons bb_getopt_ulflags came
about, it has much lower overheads than glibc's getopt_long.
