It is fuzzy. It can be interpreted, that you need -j -l ..., maybe that is the case.
-j -l should be safe tho.

-O is probably interesting for eliot ;):

"[T]he ‘--output-sync’ (‘-O’) option. This option instructs make to save the output from the commands it invokes and print it all once the commands are completed. Additionally, if there are multiple recursive make invocations running in parallel, they will communicate so that only one of them is generating output at a time."
