branch: master
commit 76f14f6ce6a74e25710ba663184f900a212b0e53

    developer-build: number of parallel jobs calculated at run time
    
    Until now, the 'developer-build' script used a hard-coded number for the
    number of parallel jobs. But this isn't generally good, because on
    different systems, we may need a different number of threads.
    
    With this commit, it now reads the number of threads from the system (using
    'nproc') when no value has been given as an option.
