I just provided a simple test case.





My real use-case is the Linux kernel build system.
The code (with a bit simplification) looks like this:





build-dirs := . drivers sound net virt arch/x86/pci arch/x86/power lib
arch/x86/lib


subdir-modorder := $(addsuffix /.modules.order, $(build-dirs))

$(sort $(subdir-modorder)): %/.modules.order: %
