    pinentry-qt4: make the accessibility part optional
    
    Check if the Qt libraries have support for QT Accessibility before using
    it. Otherwise it will raise error like these one:
    
    main.cpp: In function 'int qt_cmd_handler(pinentry_t)':
    main.cpp:220:51: error: 'class QAbstractButton' has no member named
    'setAccessibleDescription'
