The proper solution is, I think, to encapsulate toolchain variables/definitions into a package, and update the build system to not assume anything about toolchains. In a proper language, I'd create like a `class Toolchain` with everything the system would need to know to use a toolchain, and then pass a `Toolchain toolchain` to all invocations that need to do anything with a toolchain. Now this is not possible with make, but I hope it can be simulated using "fake namespaces" and something like a `$(TOOLCHAIN)_COMPILER` kind of setup.

That would require some major surgery of the build system, but I think it will come out better in the end.

After that is done, fixing so that hsdis/binutils can be compiled with gcc on Windows will be a trivial side-effect.
