Please either fix the Makefile dependency issues, or disable parallel cleaning.

I spent two days with this after my possible fix (running make clean with -j1 did not fix the problem).
One reason for the persistance of the bug is: the build does not fail in clean anymore, but in the build target instead. For the same reason.
The "cause" of the underlying problem is the fix for debhelper bug #894573 (building with -Oline make option). Or at least, if I drop -Oline from the make build calls, the package builds ok.
Unfortunately, there is not much history on the reasoning behind adding -Oline to DH's make build call. Can any of you provide some background information?
And: I am aware of the real underlying cause might possibly being a dependency flaw in nx-libs's highly complicated Makefile target stack. However, I spent two days now cleaning that up but to no avail.
I'd be happy to get some clue from any of you. I also Cc: one of our other upstream devs to follow our discussion here. If any of you dislikes being Cc:ed directly in this thread, please let me know.
