`make xconfig` fails with following linking error of qconf binary: g++ -lQt5Widgets -lQt5Gui -lQt5Core -o qconf qconf.o zconf.tab.o /usr/bin/ld: qconf.o: in function ConfigList::metaObject() const': qconf.cc:(.text+0x3eb): undefined reference to QObjectData::dynamicMetaObject() const' /usr/bin/ld: qconf.o: in function `ConfigList::qt_metacast(char const*)': link error. which is caused by the wrong order of the linked objects/libraries so this patch reorders the linker's arguments which makes the qconf compile again.
