Bug#808822: insufficient flags in pkgconfig --cflags

[Goswin von Brederlow <goswin-v-b@web.de>]

Package: qtbase5-dev
Version: 5.5.1+dfsg-10
Severity: normal

When building a trivial test case the following error appears:

% g++ -O2 -W -Wall -g $(pkg-config --cflags Qt5Widgets) -c foo.cc 
In file included from /usr/include/x86_64-linux-gnu/qt5/QtCore/qcoreapplication.h:37:0,
                 from /usr/include/x86_64-linux-gnu/qt5/QtWidgets/qapplication.h:37,
                 from /usr/include/x86_64-linux-gnu/qt5/QtWidgets/QApplication:,
                 from foo.cc:1:
/usr/include/x86_64-linux-gnu/qt5/QtCore/qglobal.h:1067:4: error: #error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC (-fPIE is not enough)."
 #  error "You must build your code with position independent code if Qt was bui
    ^

Why isn't -fPIC included in the cflags?
