ok, another attempt to the build_opt_tbl problem:

- create temp files and move them afterwards
- remove dummy option -b
- fix usage
- drop implicit creation of .c file if no --option is specified.

Now let's see if this fixes the issue. :-) We don't want to take 24s
instead of 6s to build an image reliably (Yes, yes, I know Tiano takes
over 20 minutes)
