The whole point of not bootstrapping the tools for cross compilation is to 
remove as much as we can of the bootstrapping. Right now in 5.15, the only 
tools that really need bootstrapping are qmake and moc. And for 6.0 once the 
build system switch is merged, we can proceed to un-bootstrap qmake too and 
that removes one full level of bootstrapping.

That will leave us with only moc needing bootstrapping. We can therefore 
remove libQt5Bootstrap.a and minimise the amount of work needed to keep the 
bootstrap working.
