coin: Remove dead code that used to build host Qt in a cross-build

We don't build a host Qt during a cross-compilation build for a few
years now. Instead we reuse the prebuilt host from the platform
dependencies. This was left over to allow gradual porting to the new
way of using platform dependencies, which is now long done.

Remove the code to ease maintenance.
