After some more investigations, I discover that this segfault caused
by that uClibc 0.9.30.1 definitely uses argv[0] inside getopt &
getopt_long. In other words, uClibc always requires valid argv[0]
pointer in case of it needs to output message in _getopt_internal_r().
But some applets, as it mentioned in libbb's getopt32, don't have
valid argv[0]...

I can't imagine any correct & small workaround yet, maybe Denys can
help us find allowable solution?

Regards,
   Leonid
