Hi Tomo,

This is the same commit I just fixed the description in the commit since
it said the illegal address was passed when there are non-option args.

This patch fix the case where there were no non-option arguments and then
lld_init() was passed an illegal address.
I noticed that all non-option arguments are passed to each lld but not in use.
Maybe its something that can be removed?

Thanks,
Roi
