Help with mdk4 FTBFS when building in parallel
Hello team,
I need help investigating why mdk4 randomly fails to build when in
parallel, I've been through the build log and couldn't spot anything.
The failure rate with -j16 is around 85%, I couldn't reproduce the
issue with -j1.
I also can't reproduce the issue directly in the upstream code with
make -j16, this just happens to me when under sbuild (it could have
something to do with the IO performance of schroot + eatmydata +
tmpfs).
My guess is there's something wrong in the Makefile's dependencies,
but I can't point to what exactly.
This same issue is also affecting mdk3, though with a much lower
failure rate (it succeeds most of the time on my machine).

The build log is too big for me to add to paste.d.n, so please try to
build it in your machine to reproduce.
Thanks,
