继续阅读强制目标 https://www.gnu.org/software/make/manual/html_node/Force-Targets.html，我希望有一个解决方案如下：
如果规则没有先决条件或配方，并且规则的目标是不存在的文件，则 make 会在其规则运行时假设该目标已更新。这意味着依赖于该目标的所有目标将始终运行其配方。
因此，我创建了一个空目标force-rebuild-hash-file:.
就这样SHA512SUM当调用此目标或时，文件将始终被重新创建distrib目标取决于它。
我想总体上已经解决了，如果没有，请随意发表评论。
如果您或我本人发现任何错误，我将更新此答案以反映它们。
为了消除我遇到的一些代码的重复这个答案 https://stackoverflow.com/a/27132934/1997354并应用它。
我改名了SHA512SUMS to SHA512SUM，没多大关系，但是我觉得用的比较多。
I found $@打印目标名称是跟踪正在运行的目标的好方法。例如，如果SHA512SUM不存在，我们这样安装：
make install PREFIX=./test
我们得到了一个非常好的概述（输出）：
echo && echo Target: check && echo
Target: check
if [ -f SHA512SUM ]; then ( echo && sha512sum --check SHA512SUM && ( echo && echo "Ok. You may use 'sudo make install' or '(sudo) make install PREFIX=SomeDir' command now." ) || ( echo && echo "ERROR: Files hash sum mismatch!" && echo && exit 1 ) ) else make --file=Makefile SHA512SUM; fi
