GNU Make fork with D support

[Brian]

Hello --

Some of the long tail of the dis/assembler thread got me thinking 
about D tooling, or, more precisely, external tools that could 
help aid D usage in other projects.

I stumbled upon this page in the wiki:
https://wiki.dlang.org/Build_systems

And noticed that the only thing that provides plain ol' Makefiles 
is Reggae. But that is listed as alpha software.

So I went ahead and added D support to GNU Make: 
https://github.com/ibara/gmake-d
I am unsure how welcoming such a change would be to upstream, but 
this is an entirely vanilla GNU Make just a few additions (the 
file dlang.diff in the repo will tell you all the changes 
needed). Clone, build, install, and away you go.
