    Reduce importance of qtdir option, default to ''. · 02c616cb

    The qtdir setting took on much less importance with Qt 5.  We've never
    officially supported building Qt 5 with kdesrc-build, and qmake and
    cmake both use qmake or similar Qt-provided config information to find
    Qt, rather than using the unsupported QTDIR environment variable.
    
    As a result, default the value to an empty string (interpreted as use of
    system Qt) and stop adding it automatically to the environment variables
    defined during the build.  If set, it will continue to be used for now.
    
    This also helps the environment setup driver detect when it should look
    for the system Qt5 qmake.
