The target tried to execute a non valid shell script
and there was a possibility to fatorize the creation
of the proto file instead of repeating it in all
the actions that required.
when sbase-box is executed without argument, the check sbase-box
options doesn't verify the argument count leading to a segfault.
Add a check on the argc before parsing sbase-box options (currently
only `-i`)
The Makefile rule was too complex and these cases is better to just
move it to a script where will be eassier to use sed properly
and not looping over all the files 4 times.
