Merge branch 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-1 into master-integration

* 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-1:
  configure: Don't assume that QMAKE_CXX will be found at the start of line
  Refactor GCC mkspecs to share more configuration options
  Add manual test for mkspecs to visualize the effect of the final config
