Local fix

• remove ITM_THREADSTACKSIZE
  

Problem summary

• On 64-bit platforms, ITM_THREADSTACKSIZE manipulation is
  defective and can result in improper or insufficient program
  stack storage, leading to any of the following messages in the
  Tivoli Monitoring process RAS1 log:
   KDE_THREADSTACKSIZE=ITM_THREADSTACKSIZE="1024"
   "static_constructor" . Comm thread stack size is
  17592186044416K
   "build_sdb" . HTTP thread stack size is 17592186044416K
   "NewSDB" . RPC thread stack size is 4096K
   "KDHS_Spawn" . Unable to create tqa service thread: 11
   "KDEBP_Listen" . Status 1DE00001=KDE1_STC_NOMEMORY
   "KDCS_UseFamily" . status=1c01001a, "main storage exhausted"
