[Lazarus] suggestion for lazbuild

[FreeMan]

in osx yosemite

./lazbuild --quiet  -> hints still showing billion "sender not used" 
massage. Not counting line but with --quit parameter or without this 
parameter not change output lines

if not add "--max-process-count=8" parameter,
show this line, and freezing. only one line
SetPrimaryConfigPath NewValue="/Users/freeman35/.lazarus" -> 
"/Users/freeman35/.lazarus"

after add, in 1min 29 second ide builded.many 3party components added. 
this is so fast on my system, nearly 50% faster then before added this 
parameter.
