Missing Build Dependence: _freeze_module.c

Bug report

Bug description:

Build CPython by running "make".

Then a dummy pointer field to the end of struct PyConfig in Include/cpython/initconfig.h:

void *dummy;

Then, run "make" again. This time, you'll get a weird error from _freeze_module run as part of the build. Exactly what error you get will depend on how much you change the size of struct PyConfig and the system you're on. On my Linux system, sometimes it gave me an error about attempting to open() NULL (because the stack variable "inpath" from main() in _freeze_module.c was clobbered). Sometimes it gave me a path error.

Remove Programs/_freeze_module.o. Run "make" again. Marvel as this time make succeeds.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux

在将 dummy 字段添加到 Include/cpython/initconfig.h 后，使用 make 重现该问题，然后检查 Programs/_freeze_module.o 的构建条目和 _freeze_module.c 依赖关系。当第二次 make 能够重新构建受影响的目标并成功完成，且无需手动删除 Programs/_freeze_module.o 时，即表示完成。
