Bug 540085 - Deadlock in ToolChainManager init

Browse source 
- modify ContainerGCCToolChainProvider.init so that the
  CBuildConfigurationManager.recheckConfigs() call is done
  within a separate job so the init() call will return
  without causing deadlock
- do the same for ContainerTargetTypeProvider
- modify CBuildConfigurationManager initProviders() method to
  be synchronized
