dist/bin/actonnow invokes$(STACK)at this line, and$(STACK)is defined to usecompiler/tools/zig-cc.sh/zig-cxx.sh, which abort whendist/zig/zigis not present. Because the target prerequisites still do not include$(DIST_ZIG), runningmake dist/bin/actondirectly (or in a parallel flow that has not built Zig yet) can fail nondeterministically before the build starts; declaring the Zig artifact as an explicit prerequisite would make this target reliable.Useful?
