This is no concern at all ;-)
You see a DMD compiler is already _required_ to build DMD. We 
simply use the same host compiler to compile build.d. The CIs 
enforce that we can always compile DMD with the minimum host 
compiler and similarly they also enforce the same for build.d.

However, while we can build DMD and run its unittest without Make 
now, druntime and Phobos don't have the equivalent of `build.d` 
and `test/run.d` and some of the lesser used DMD Makefile targets 
like the docs target haven't been ported either, so it will still 
take a bit of time until we're in a post-make era.
