为什么GNU让流程挂起？

Question

TL; DR：

在全新的Windows 10安装中，我安装了ARM DS-5 v5.26.2开发工具。我使用它的make.exe来构建我们的项目，无论是从Cygwin命令行还是从Eclipse IDE的构建设置。

我们的Makefile包含以下行：

uname_result := $(shell uname -s)

但只要make到达此行，就会卡住。这发生在bash终端以及Window的命令提示符上。

更新3：

经过更多问题排查后，问题似乎是DS-5的make实用程序本身。我在我的Cygwin安装中添加了make，然后使用了那个，现在我的构建运行正常。

现在问题是为什么ARM的版本在我的Win 10机器上不起作用，以前它在Win 7上运行良好。

长版：

在PC上使用Windows 7两年后，我刚刚在我的工作PC上完成了Windows 10的全新安装。在过去的两天里，我正在重新安装我们的工具并恢复体形。不幸的是，我现在坚持make让我感到头疼。

我们使用ARM的DS-5工具集开发嵌入式固件。该项目是一个Makefile项目，因此我们不使用内置的Eclipse构建器。为了在Eclipse环境之外构建项目，我安装了Cygwin以方便bash CLI。 make和clang都是DS-5安装的一部分。

当我在项目的make表单CLI上运行Makefile时，执行会无限期地被卡住。

[...在问题揭示过程后删除了一个长篇故事...]

在追查问题的根源后，我发现问题在于这一行：

uname_result := $(shell uname -s 2>NUL)

为了简化它，我验证了问题是shell命令本身。我使用以下命令制作了一个非常简单的Makefile：

uname_result := $(shell ls)

当使用make -d处理makefile时，当它到达该行时，我得到以下内容：

CreateProcess(C:\cygwin64\bin\ls.exe,ls,...)
Main thread handle = 000000000000009C

为什么make执行shell命令？这个完全相同的脚本曾经在迁移之前正常工作。

更新1 w /更多信息：

我的系统中只有一个make.exe，位于C:\DS-5_v5.26.2\bin。

我创建了一个简化的makefile Makefile.tmp：

.PHONY: help
help:
    echo ====================== TESTING ======================
    uname_result := $(shell ls)

我从Cygwin的bash CLI处理这个makefile：

$ /cygdrive/c/DS-5_v5.26.2/bin/make -d -f Makefile.tmp help

我得到了大量的诊断信息：

因此，正如您所看到的，它既不执行echo命令也不执行ls命令。如果我注释掉shell命令，我会看到TESTING消息回显给终端。

显然，DS-5的make.exe是为Windows而构建的。从Cygwin bash调用它应该有问题吗？如果是这样，那么在Win 7机器上如何运作呢？

更新2 w /更多信息：

我重复测试，这次是从Windows＆＃39; CMD提示。我用ls命令替换了b shell行中的dir命令。令人惊讶的是，同样的行为也发生在CMD上！

所以，显然，问题是 make＆＃39; shell函数调用。
