We have some cache variables that are used in our qt.toolchain.cmake
toolchain file, for example QT_CHAINLOAD_TOOLCHAIN_FILE. When CMake
runs a configure test with try_compile, our toolchain file is included
again, but only a restricted set of variables is available.
Add the variables that are used in our internal toolchain file to
CMAKE_TRY_COMPILE_PLATFORM_VARIABLES. This makes them visible for
try_compile calls operating on source files.
Also pass the variables via the environment to support try_compile
calls that operate on whole projects.
