>From e227572a57eaa6c14636c1d197a6d40254bcfa5c Mon Sep 17 00:00:00 2001 From: Akira Yokosawa <akiyks@xxxxxxxxx> Date: Tue, 6 Jun 2017 00:24:15 +0900 Subject: [PATCH 2/5] CodeSamples: Use $(MAKE) for recursive make For recursive make, "$(MAKE)" is recommended.[1] By this change, options such as "-j4" can be transferred to builds under subdirectories. Also convert the list of recursive "make"s to a "for" loop by defining a variable "subdirs".
