DUB: use stable DMD

[wilzbach]

Change the DUB invocation to rely on STABLE_DMD

Tried this as well, the assert_writeln_magic script failed to compile for me (w/ 2.069.0). Also stable_dmd needs to be in the dependencies for the target.

Hmm yeah I think libdparse needs at least 2.071 due to its dependence on std.experimental.allocator.
I couldn't find an existing target to build the latest PHOBOS_LIB in this Makefile, hence I added it.

Does this help you?

[MartinNowak]

No, our policy for tools and external dependencies is to always use stable compiler versions to avoid complications/incompatibilities.
We might update STABLE_DMD to 2.071, I guess.

Ok.

With the PIC changes on Ubuntu, 2.072.2 seems a more reasonable choice as "stable" version.
See this PR for a previous precedent: dlang/dmd#6411

Do you run the style Makefile target there? This file in out seems to be a left-over ...

Mmh, works now after recleaning phobos.
