+    #       LLVM is smart and doesn't need a compiler to cross-compile code.
+    #       With that said, Busybox uses Kbuild, which hard-codes variables like
+    #       CC to GNU-based tools, which is not what we want. The following sed
+    #       hack should do the trick, but I wonder if there's a better solution.
