Qt installer .pc files unusable due to spurious prefix

From the directory where Qt has been installed / gcc_64/lib/pkgconfig:

~/Qt/6.8.3/gcc_64/lib/pkgconfig$ grep "work" *.pc
Qt6Charts.pc:prefix=/home/qt/work/install
Qt6ChartsQml.pc:prefix=/home/qt/work/install
Qt6Concurrent.pc:prefix=/home/qt/work/install
Qt6Core.pc:prefix=/home/qt/work/install
Qt6DataVisualization.pc:prefix=/home/qt/work/install
Qt6DataVisualizationQml.pc:prefix=/home/qt/work/install
Qt6DBus.pc:prefix=/home/qt/work/install
Qt6Designer.pc:prefix=/home/qt/work/install
Qt6Graphs.pc:prefix=/home/qt/work/install
Qt6GraphsWidgets.pc:prefix=/home/qt/work/install
Qt6Gui.pc:prefix=/home/qt/work/install
Qt6Help.pc:prefix=/home/qt/work/install
Qt6LabsAnimation.pc:prefix=/home/qt/work/install
Qt6LabsFolderListModel.pc:prefix=/home/qt/work/install
Qt6LabsPlatform.pc:prefix=/home/qt/work/install
Qt6LabsQmlModels.pc:prefix=/home/qt/work/install
Qt6LabsSettings.pc:prefix=/home/qt/work/install
Qt6LabsSharedImage.pc:prefix=/home/qt/work/install
Qt6LabsWavefrontMesh.pc:prefix=/home/qt/work/install

All .pc files contain references to spurious "/home/qt/work/install" prefix, making them unusable.
