ltp-ddt makefile的思考

make autotools

在Makefile中
include $(top_srcdir)/include/mk/automake.mk
automake.mk中有autotools目标

./configure --host=arm-linux-gnueabihf

看了一下生成的时间和内容，貌似是config.status: creating m4/Makefile这个Makefile
但是找遍代码，没有看到哪里用到了，高度怀疑配置的内容在include/mk/config.mk和include/mk/features.mk中

而Makefile还是用的自己的那套系统。
