In modularized documentation, some links to other modules' pages are generated with the wrong module name and directory.

For example:
http://doc-snapshot.qt-project.org/qt5-stable/qimageioplugin.html#Capability-enum
...has a link to QFlags.

In the single directory output, the link works, but in modularized documentation, the link is generated to be
"qtgui/qflags.html"
it should be
"qtcore/qflags.html"
