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

在將 dummy 欄位新增至 Include/cpython/initconfig.h 後，使用 make 重現問題，接著檢查 Programs/_freeze_module.o 的建置項目與 _freeze_module.c 的相依性。當第二次 make 能重新建置受影響的目標並成功完成，且不需要手動刪除 Programs/_freeze_module.o 時，即表示完成。
