-j[JOBS], --jobs[=JOBS]
Specifies the number of make jobs to run in parallel when compiling Ruby. If the -j option is provided without an
argument, make will allow an unlimited number of simultaneous jobs.
But the code always treats the argument following --jobs/-j as the number of make jobs. The command-line help is pretty similar:
-j[JOBS], --jobs[=JOBS] Number of jobs to run in parallel when compiling
Where [VALUE] usually mean 'optional', by convention.
