There, we store information specific to the build of qtbase.
It's passed to CMake when you call qt-cmake / qt-configure-module to 
build further parts of Qt.

CMake allows only one toolchain file. To run above scripts with an 
additional toolchain file, pass -DQT_CHAINLOAD_TOOLCHAIN_FILE=<filepath>.
