I was initially a bit worried about this because it makes the build
depend on the existence of the d/ directory.  But it doesn't look
like we try to ship separate tarballs for specific source languages
any more, so that's probably not a problem.

"and being"?  Does this mean "that are being"?

Please reflow the .def so that these fit within 80 chars.

OK otherwise if no target maintainer objects to the changes to their port
(I think they've had plenty of time already :-))
