v8: give sensible error message if v8 sources are not checked out
A common error for developers attempting to build qtbase for the first time is to miss cloning the v8 submodule. Let qmake check for existence of the sources so we get a sensible error at qmake time, rather than a relatively inscrutable error at make time.
