Bug report

Bug description:

I have an error in test.test_tools.test_makefile.TestMakefile.test_makefile_test_folders:
[test_makefile_test_folders_log.txt] (https://github.com/user-attachments/files/17328017/test_makefile_test_folders_log.txt)

Such change helps:

Is it correct change of Makefile.pre.in and can be merged to main?

I'm unable to reproduce this; can you provide a minimal reproducer?

[efimov-mikhail]

Actually, I can't reproduce this by myself.
I definitely had a problem on some commit from main branch few days ago.
But today I can't reproduce an issue not only on HEAD of main but also on other commits.
