The description is wrong, as it's from the time before dropping the suffixes and migrating to the upstream recommended qtchooser solution. Fixing the description. The qmake-qt5 package Recommends installing qtchooser to have /usr/bin/qmake, while the qtchooser Suggests qt5-default which sets the default configuration (qt4-default sets /usr/bin/qmake to point to Qt4's qmake).
