Yah, that's a classic. Usually multi-stage bootstrapping is
used. One simpler way to accelerate that is to just download
the last version's binaries (which is what
https://github.com/D-Programming-Language/dmd/pull/4645 does).

I guess that is fine if the binaries exist for the new platform.
Otherwise it should be just a screenful of code to iterate
through the chain of versions required, calling the build process
each time - either update_sh or perhaps it could be added to
Cybershadow's tool.
