# 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.
# ~ahill
sed -i "s/?*= \$(CROSS_COMPILE)/?= /" Makefile
# 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
sed -i "s/main()/void main()/" scripts/kconfig/lxdialog/check-lxdialog.sh
# NOTE: AR, CC, and HOSTCC are required here due to GNU dependencies. ~ahill

# NOTE: Busybox doesn't have a proper DESTDIR, so we just set CONFIG_PREFIX

# NOTE: Once again, AR, CC, and HOSTCC are set because we're using LLVM and
# not GCC. ~ahill
