Unfortunately not. We need at least two steps to build a gcc7/8/9. First 
we need a gcc5/6 built with base gcc (4.2.1) then we have to use this 
built gccX to build gcc7/8/9.
I had situations where I needed three steps, 4.2.1 -> 4.9 -> 5/6 -> 7+

My testing is limited to fix bootstrap atm. But x-mas might bring some 
testing time too for a more verbose statement.

Thanks,
Andreas
