Oh, right, the problem might be that -W[no-]undef causes llvm to complain.

That is more difficult to deal with.  Not completely ideal, but something like

ifneq (,$(filter -Wundef, $(WARNING_FLAGS))

Or alternatively, clobber WARNING_FLAGS as before only if using clang, and use the proposed new code if not, and let someone who cares about the combination of zero / linux / clang improve that part.
