Python3 at runtime identifies the uuid backend to use to implement safe time-based UUID generation functions. When the python _uuid extension module, /usr/lib/python3.7/lib-dynload/_uuid.cpython-37m-<arch>.so is not found, the fall back is to use a pure python implementation. - If uuid.h from util-linux is available at build time, the _uuid module is built and used. A Buildroot patch allows us to disable this build-time check and never build the _uuid module. With the bump to python 3.7, an optional dependency on util-linux was added to build the _uuid module. However, this may lead to circular dependencies. To break this circular dependency, we can disable the build of the _uuid module and always use the pure python implementation.
