'$(@F)' is the file-within-directory part of the file name of the
target. If the value of ‘$@’ is dir/foo.o then ‘$(@F)’ is foo.o. ‘$(@F)’
is equivalent to ‘$(notdir $@)’.

That is basically what it does now in the current implementation, but,
you don't need to pass the full path and no output file, since it knows
where to get the file and where to save it to.

If you are curious about the current python script, I've pushed it here:
https://github.com/leitao/linux/blob/netdev_discuss/tools/net/ynl/ynl-gen-rst.py

I can easily remove the paths inside the python file and only keep it in
the Makefile, so, we can use -i $< and -o $@.
