+    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'
