GNU Make 在什么情况下会更改堆栈大小，为什么？

Question

考虑这个 makefile：

.PHONY: all

all: dummy test
    ulimit -s

include dummy

dummy: test
    touch dummy

当我运行它时，我得到：

$ make -v
GNU Make 4.1

$ touch test; make
touch dummy
ulimit -s
unlimited

但是，如果我删除 include dummy 或将 touch dummy 替换为 true，则 ulimit -s 会得到 8192。怎么回事？
