Dear maintainers,

Please consider my patch at https://salsa.debian.org/openstack-team/third-party/python-eventlet/-/merge_requests/1 for using DEB_BUILD_OPTION_PARALLEL instead of nproc to respect Debian Policy 4.9.1 [0]

Using `nproc` ignores the value of `parallel` that may be set in DEB_BUILD_OPTIONS
