Remove default argument from declarations of qHash as friend
It's illegal in C++11: § [dcl.fct.default] "If a friend declaration specifies a default argument expression, that declaration shall be a definition and shall be the only declaration of the function or function template in the translation unit." Clang is starting to enforce this, thus it's making qtbase not compiling.
