This is the corresponding change to the one on main NuttX repo. In this case this involves splitting the build of libapps.a into: a) building all applications (which is safely parallelizable), b) adding each application's object files to the archive in turns (serial by nature). This removes the need for the flock used to protect the parallel build.
