Title: Qt 5.15.3 version bump with binary path changes
Author: Andreas Sturmlechner <firstname.lastname@example.org>
Up until Qt 5.15.2 we were using qtchooser to provide unversioned links to Qt
binaries in PATH, like qmake, moc, qmljs etc. Starting with 5.15.3  such
links will be installed by each respective Qt package and '5'-version-suffixed,
e.g. qmake becomes qmake5, qml becomes qml5 etc., mirroring Qt6.
If you develop with Qt5 and rely on unversioned binaries for your workflow,
dev-qt/qtchooser as a tool for quickly switching between multiple Qt
installations (e.g. Qt3, Qt4 and Qt5) can still be manually installed. The
'default' Qt version in PATH is then controlled via config in
Otherwise, dev-qt/qtchooser will be slated for cleanup on your next
emerge --depclean run.
