Patch:
- 0001-Adjust-library-header-paths-for-cross-compilation.patch
comes from buildroot [1], but they removed it as they switched to Python 3.12,
however Python 3.11 still supports distutils, but it is marked as deprecated [2]
and it will be gone in 3.12. So, don't rebase it this time as this patch does not apply
anymore due to this commit [3] and sooner switch to more up-to-date Python3 version.
