commit 7740e253d0e97f85a21b4dd7061463cb1d4aa384

    Fix ./validate with GHC 7.6 as bootstrap compiler.
    
    7.6 deprecated the Control.Concurrent.QSem module (to be removed later,)
    but according to Patrick it was actually un-deprecated. As a result,
    validate fails if your bootstrap compiler is 7.6, since it throws a
    DEPRECATED warning.

+-- NB: we specifically ignore deprecations. GHC 7.6 marks the .QSem module as
+-- deprecated, although it became un-deprecated later. As a result, using 7.6
+-- as your bootstrap compiler throws annoying warnings.
