    # NOTE: Like we did with musl before, we don't set CROSS_COMPILE because
    #       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.

    # NOTE: Apparently, Busybox fails to properly check for ncurses since the
    #       test compiles a main function without a return value type, causing
    #       the compilation to fail. This patch fixes the issue by making the
    #       returned type "void". This doesn't actually affect the build, but
    #       I'm not sure where else to put this. ~ahill
