Sounds like a great idea!

I can certainly build the GDC toolchains*. But I guess the first thing
you'll need if you want to use Dreamcast, NDS and other low memory
systems is a @nogc druntime port? I had a look at this some time ago and
there's some work to be done until we can build a druntime completely
without GC.

or better: also provide build scripts. We now use docker.io containers
to build the binary GDC toolchains. Building a toolchain with the latest
GDC version is as simple as running one docker command:

docker run
-v ~/shared-dir/:/home/build/shared #results will be saved here
-t jpf91/build-gdc /usr/bin/build-gdc build

It should be easy enough to add support for console toolchain build
