[New-bugs-announce] [issue16238] Automatically remove build directory when build options changed

[anatoly techtonik]

New submission from anatoly techtonik:

After build options in setup.py is edited, command `python setup.py install` doesn't remove build directory and uses its cached content. This behavior is non-obvious and leads to errors.

The proposal is to calculate hash from build configuration, save it in build directory, and regenerate build dir when hash doesn't match.
