Running all.sh --force on a clean repository removes programs/fuzz/Makefile

[AndrzejKurek]

This forces the user to discard programs/fuzz/Makefile changes to regain a working repository copy.

Same with Makefile, programs/Makefile, etc. This is because some components use CMake in-tree, and that overwrites **/Makefile. It's documented. The point of --force is to say you don't mind this.

Why is this issue about programs/fuzz/Makefile specificatlly? Just the one you happened to notice, or is it / should it be treated differently from the others?

[AndrzejKurek]

Oh, maybe I wasn't specific enough. The script fails to execute and does not clean after itself on a fresh repository:

./tests/scripts/all.sh test_full_cmake_gcc_asan --force
cp: cannot stat 'include/mbedtls/mbedtls_config.h.all.bak': No such file or directory
git status
On branch pkcs5-no-md
Your branch is up to date with 'AndrzejKurek/pkcs5-no-md'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    programs/fuzz/Makefile

no changes added to commit (use "git add" and/or "git commit -a")

[gilles-peskine-arm]

Ah. And there's more. Using --force on a clean repository causes another error:

cp: cannot stat 'include/mbedtls/mbedtls_config.h.all.bak': No such file or directory

And after that, programs/fuzz/Makefile is deleted. So there are in fact two bugs here. Probably unrelated, but worth fixing together.
