Please stop pointing to that article. It should be called "GNU make
considered harmful" if anything, since most of the content is a direct
result of issues in that tool. As I said earlier in this thread: LLVM is
nowhere big enough in terms of subdirectories that recursive make is a
significant contributor to build time.
