[Buildroot] [git commit] support/misc/toolchainfile.cmake.in: add definitions needed by Qt6

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=b4cb2d3ebc6e2c08fb79e1c195a5028ed24a0cde
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When compiling Qt6 applications for the target, CMake needs to have
two variables defined to find the host installation of Qt. These two
variables are unconditionally defined, regardless of whether Qt6 is
enabled in the configuration or not, as they do no harm when Qt6 is
not present/used.
