On SPARC systems running Linux, individual processors are denoted with "CPUnn:" in /proc/cpuinfo instead of the usual "processor NN:" so that the current regexp in ncores() returns 0. Extend the regexp to match lines with "CPUnn:" as well to properly detect the number of available cores on these systems.
