A package may run git as part of its build process, and if the package source code is not from a git checkout, then git may traverse up the directory tree to find buildroot's repository directory (.git).
For instance, Poetry Core, a Python build backend, will read the contents of .gitignore for paths to exclude when creating a Python package. If it finds buildroot's .gitignore file, then Poetry Core will exclude all of the package's files[1]. This exports GIT_CEILING_DIRECTORIES for both package and host builds so that git will not traverse beyond $(BUILD_DIR)/$(BUILD_DIR_HOST).
