    Linux cpuinfo count fixed for SMP PPC processors (bgo #621831)
    
    libgtop processor count has been simply determined by the number
    of sections in /proc/cpuinfo split by \n\n. On PPC processors
    supporting SMP after the per-cpu description for each core a
    new section is listed (after \n\n) with the common attributes
    of the cores [1]. Work around this by only counting a section
    as describing a CPU if it contains "processor" to fix bug #621831 [0]
