I understand, but aside from qmake, I don't know of any build system that 
allows for building both host and target in the same build. That means 
whatever we use in Qt 6, we'll a separate build for host tools when cross-
compiling.

I don't see a problem in requiring the same version in the host and the target 
being built. But if this is not possible, then we'll need to have an extra 
step when preparing for cross-builds that bootstraps the host tools.
