Bug 531125 - Tupled gcc toolchains should not be the local default

Browse source 
- change ToolChainManager so that when creating the types map for
  the first time, make it a LinkedHashMap instead of HashMap so
  order of input is preserved (first in = first out)
- fix GCCPathToolChainProvider so that it adds non-tupled gcc
  to the ToolChainManger before adding any tupled version
