Adjust the parallelism of tail_build to be max(max-process, num-cpus)
tail_build run mostly by itself and wrap a dozen of module,
using just MAXPROCESS for the parallelism force to limit NB_CPUS
in order to avoid a NB_CPUS x MAXPROCESS scenario.
This mitigate this problem, until we don;t need MAXPROCESS anymore
and NB_CPUS becomes the only driving force.
