Fix compilation of Qt Concurrent with gcc 4.3
GCC 4.3 had support for decltype but not the new function syntax (which
we call "auto function" for short). That meant the code did not compile.
qtconcurrentrun.h:105: error: expected initializer before ‘->’ token
Task-number: QTBUG-28984
Change-Id: I792276ec59c4f6e73f6137c517636e70c71ed849
