Interesting

Haven't noticed it 

This may come from 

    sed -e "s:QMAKE_CFLAGS_RELEASE.*=.*:QMAKE_CFLAGS_RELEASE=${CFLAGS}:" \
        -e "s:QMAKE_CXXFLAGS_RELEASE.*=.*:QMAKE_CXXFLAGS_RELEASE=${CXXFLAGS}:" 
\

or something

Open a bug if you like so the rest of qt herd will be informed about this :)
